RE: Slide seals one wiper or two

No, Wiper seals are just that. They fill the gap between the room and the cut out. They do not SEAL the room in or out. The D seals do that. If a double wipe seal will fit, no problem using it. Doug

RE: shutting down generator with air conditioner running

After 40 years and still an RV tech, the ONLY practice I would follow is, Shut the LOAD (AC and such) OFF, then kill the Genset. Start the Genset. wait for Transfer from the ATS, Then start you AC units. The reason is, The Contacs on the ATS take a beating when starting and stopping on a LOAD. I have yet to see a failure of a Inverter or a Genset that COULD be attributed to shutting down under load. Cooling a AIR COOLED genset, I can see the advantage to running 5 minutes before shut down. But, a WATER COOLED Genset, I see no reason, any more so that running your Auto for 5 minutes before shutting it off. Inverter(Large) have cooling fan/s, so I see no reason to worry about them. Doug

RE: shutting down generator with air conditioner running

Amazing how many systems in an RV do not protect themselves but rather rely on operator for proper operation. You think the transfer switch is a no-brainer, check this out. On my ancient 1990 Winnebago, there is a rocker switch on the dash. If you push it one way, it momentarily gangs the house battery to the engine battery for an emergency start. No problems there. But if you push it the other way, it stays that way, and allows the alternator to charge your house batteries while the engine is running. BUT if the generator is also running and you do this - it will smoke your vehicle voltage regulator. This is explicitly warned against in the owner's manual. I have accidentally smoked the VR this way before. You would think there would be some kind of interlock that prevented this situation. Steve You had other things that caused your failure. Winne/Itasca used the SAME switch system from at least 1978 to mid 90's. I worked on Itasca/Winne (we were a dealer) from 1978 to 1991 when we dropped Winne/Itasca. We were a chassis shop also during that time. NEVER had VR's fail. This was thousands of Winne/Itasca's we sold and serviced. The DUAL switch was almost always left in the DUAL position by our customers. Doug

RE: Holiday Rambler Fuse location

Looking for the passenger seat fuse location for a 2016 Holiday Rambler Scepter. The fuse panel located outside below the drivers sear is not labeled and short of pulling every fuse - not sure how to find the correct fuse... Monaco used to put a label on the inside of the plastic cover of that below drivers seat fuse panel and yes, that is where the fuse is located. Doug

RE: Holiday Rambler Fuse location

This is what you need so you do not have to pull fuses to check for blown fuses.

RE: Air Conditioning Problems

Our unit is 3 yrs old and I just had an HVAC guy look at it. Domestic brand. He had to add a bunch of refrigerant. Had to add a piece to be able to do it. Much cooler now and no freezing up anymore. Did he FIX the leak the Gas leaked out of?? If not it's gonna HAPPEN AGAIN. What's a "bunch" of Coolant? They only hold 1 lb. Doug

RE: Battery or no battery????????

1. WHY would anybody NOT utilize Trailer Brakes and the break a way system regardless of the law?????????????? 2. Always install a battery, It helps keep the Power Converter from working too hard as it helps regulate the Converter output. Doug This thread the Jayco does not have a slide, but most RV's with slide rooms will not operate the slides without a battery installed. Some will, but it puts a strain on the Converter. Mine will, and the AC, and the fridge, and the WH. As for the converter. Runs all the time anyway. ALL Converters run all the time(when 120 is too the RV). It just depends on how HARD it works depending on the DC load asked of it. We have had to replace Burnt out Converters in Show Units caused by running the various items 24/5 in a show and utilizing the Converter to power the slides. Because of Show restrictions that regulate having batteries connected(you must disconnect some batteries) , we just had to hope that this load does not burn out a Converter. Since most Trailers do NOT come from the OEM with a battery, we do not install a battery for the show units. We wait until it is sold, then install a new battery. One exception, is Airstream trailers. They come with a battery from Airstream. Doug

RE: Sundance 241BH - Black water tank fell out

??? I've never heard of a floating check valve in a black (or grey) tank vent. I can see no reason for a manufacturer to install one; The only way to "overfill" the black tank is with the rinser, and in that case, it would be better to have the overflow go out onto the roof rather than overpressurizing and dropping (like yours did) or even splitting the black tank open, or flowing out through the toilet (or bathroom sink if plumbed that way). Sounds like a made-up excuse by the dealer. :S Have that dealer show you that floating check valve. In 40 years working on RV's and dropping countless tanks, I have NEVER seen anything inside a tank or connected to a Vent system in or around the tank. Every week, I think I cannot find something new that a Dealer/Tech/ customer posts that is BS. Well, this makes my week:B Doug

RE: Rooftop AC Tripping Breaker... Sometimes

Thanks for the feedback everyone. I'm sure the coils are as clean as they can be. They weren't too bad to start with, but I used a shop vac with a brush attachment to get the few items that were large enough to see. I then soaked them with a foaming coil cleaner and finished them off with a good rinse with the water hose. I did this with both sets of coils. I don't think it is the supplied voltage either. I have had the same issue at 2 different RV parks, using the generator, and plugged up at my home. I'll check the amp draw using an extension cord. That should tell me something. I don't think the coach has the amp draw on the EMS, but I know where I can borrow a meter. 50 amp EMS will NOT show amp draw when connected to 50 amp service. To test, you either connect to 30 amp or run the Genset. On Genset you will have total amp draw. Doug

RE: Battery or no battery????????

As you can see, it all depends on the circumstances. There are other states that have limited requirements on towing Trailers and brakes. I just listed some that were part of this discussion. Doug MASSACHUSETTS Every trailer having an unladed weight of more than 10,000 lbs. shall be equipped with air or electric brakes. note that it is 10,000 lbs OREGON Independent braking system not required, but combination of vehicles must be able to stop within legal limits. Every motor vehicle and combination of motor vehicles, except motorcycles and mopeds, shall at all times be equipped with a parking brake system. TEXAS A trailer or pole trailer is required to have brakes if its gross weight exceeds 4,500 lbs. A trailer with a gross weight between 4,500 lbs. and 15,000 lbs. is not required to have brakes if it is towed at a speed of not more than 30 mph.

RE: Rooftop AC Tripping Breaker... Sometimes

You have a bad compressor. Your symptoms point to that. To verify, you need a AMP draw of the compressor. Without special amp draw meter, you may be able to do a draw test. Not sure if 2001 Knights had the Intellitec EMS system that shows amp draw on the inside remote panel. If so, you can start the AC unit and watch the amp draw. You should have a baseline with other 120 appliances running. Watch the amp draw increase as the front AC starts up. The MAX increased amp draw caused by the AC should be 14 to 15 amps. Watch the amp draw in the heat. If the amps slowly increase above the 14 to 15 start up, then your compressor is bad as long as the Condensor coil is clean. If no EMS system, then you will have to get a Amp draw meter. Doug

RE: Onan 5500 fuel pump not priming

YOu say it primes and runs. then it stops and won't prime. then it primes and runs, then it stops and won't prime. The fuel pickup in the tank has a strainer (pre-strainer) just like the water pump has. If you've left old gas in the tank (Gasser) or algae has grown (Diesel) that pre-strainer may be clogged. Then there is the fuel filter it too can clog And a pinched fuel line not letting fuel through. all of those will act exactly as you have described Error code will show "No fuel". A Genset fuel pick up in the fuel tank is just a straight metal tube that is terminates right at the 1/4 tank level of the fuel tank. NO filter or strainer at all. Diesel and Gas are the same. Doug

RE: Norcold fridge not cooling

You do not need to pull the fridge to replace the fans. Standing on a ladder you can easily reach in and replace them. We camp a lot in hot weather and I did this....much better and has served us well since installed. https://www.rv.net/forum/index.cfm/fuseaction/thread/tid/29770712/srt/pa/pging/1/page/1.cfm If a 1200 is installed CORRECTLY, you cannot access the fans from the roof top or top access door if in a slide out. if you had access to those 2 fans, then the correct baffling was not installed.

RE: Trailer brakes stop working when headlights are on

Your 7 pin SHOULD have a ground wire that connects both the Truck and the Trailer. IF NOT, then the 5th hitch plate is the ground between the 2, which is NOT adequate. Do NOT connect the trailer to the truck. just have the hitch off the plate and then connect the 7 way and see if you get tow lights and brake lights and brake operation. You can move slightly a foot or so to see if the brakes grab. That will determine the ground situation without testing the 7 way plug. Usually the ground from the Trailer end is secured to a screw in lug in the 5th wheel hitch tongue. Doug

RE: Onan 5500 fuel pump not priming

Gas Gensets use about .7 gallons per hour. Connect a 1 gallon Gas can to the Gas input of the Genset and run the Genset. If it fails, then you need a new fuel pump. IF it stays running then think about a rotted supply line from the fuel tank. Doug

RE: Shore works ATS in and out on Gen power

It is a violation of the NEC to ground the neutral and shore power in the rig. Shore power is only grounded at the service connection point. The genset must have the neutral bonded to ground. Really. I have worked on motorhomes and Gensets for 40 years. The 120 pigtail coming OUT of a Genset for 50 amp and above Gensets. Has 4 to 5 wires. 2 wires are the Black HOT output 1 or 2 wires(depending on the Genset) are WHITE Neutral wires then 1 wire is the ground output. ALL go straight to the ATS or the 50 amp female receptacle(if no ATS system). At no point is the Neutral grounded... On my RV (and I think it's typical of most proper installations), the neutral and ground are bonded together inside the genset. Both connect to the genset's chassis; in my case, to a little vaguely crown shaped bit of metal that attaches where the main genset chassis ground tie attaches to the genset. If measured with an ohmmeter, the neutral and the ground lines coming out from the genset should show a short. It is true that they should not be connected together at any time for the shore power cord, which is the main reason the transfer switch must switch the neutral as well as the hot(s). I am talking AFTER the Power source. NOT internal of a Genset. From the discussion, it was making it sound like the connections NOT from the Internal wiring of the Genset, but at the ATS and interior Breaker Box, you combine the Neutral and Ground. You do NOT do that. Doug

RE: Onan 5500 fuel pump not priming

Thanks Doug...so the prime seems to be intermittent. It was just running for about 5 Minutes then stops. After it stops all I hear when I go to prime is a click...no fuel Moving. If I wait about 10 minutes it’ll prime and start again, run for about 5 min then shut off. My fuel tank is between 1/4 and 1/2. Get the fuel tank above 1/2 tank and retest. Your 1/4 tank pick up may not be accurate. Doug

RE: Onan 5500 fuel pump not priming

The most common problem with a 10 year or older Motorhome, is, the rubber fuel line from the Fuel tank pick up tube to the Genset has dry rotted. The small cracks cause air thru the rubber and that disables the fuel pump from getting its prime to pull fuel. A quick way to determine this is to connect a gallon gas can and remove the existing fuel line from the genset and connecting a good new rubber line and see if the Fuel pump then primes. Usually it will. Doug PS, If you hear a click, that may be the fuel cut off solenoid opening. BUT, you should also hear the Fuel Pump rattling trying to pump. This would mean your above fuel line is good. Also, I believe the fuel pump has a pressure cut off. When the fuel pump cannot pump, its internal pressure switch shuts off. When testing the fuel prime you need to disconnect the metal line at the Carb input. Onan and other Genset makers require a LOW pressure fuel pump which is what Onan makes and supplies. The aftermarket Automotive similar looking pumps are 2 to 3 times the PSI of a genset pump.

The Neutral wire goes straight to the inside 50 amp breaker panel from the ATS system to the Neutral BUSS Bar. The GROUND goes straight to the GROUND on the Inside Breaker BUSS bar. At no time are the Ground and Neutral connected. I am NOT an expert on the NEC or how it relates to RV systems. ALL I KNOW, is, HOW 120 systems are connected and used in RV's. ALL RV's have a separate Neutral BUSS Bar and a GROUND BUSS bar. Last, ATS systems do NOT look for true 50 amp out of phase HOT to operate. 50 amp EMS systems do. Doug
