RE: Inverter/Alternator Question

Ditto Richard and Clay. No guessing with a voltmeter and the Monaco line has a relay this fails often enough that I carry a rebuilt one. Yes, I took it apart and repaired mine. For some excellent information do a search for BIRD systems on rv's. You should have no problem running the inverter with the engine running. Do the test Richard describes and you will know in five minutes what is up.

RE: Chasing electrical gremlins - GFCI outlet puzzle

The breaker did not trip because there was not enough of a load. I know it is hard to visualize seeing a voltmeter read 120 volts and not have enough power to run a light. I cannot tell you how many times I have seen techs caught by trusting a digital voltmeter. My understanding is that an analog meter avoids this false reading? Does this also apply to little cheap meters or good ones like a Simpson? Even a cheap Radio Shack analog meter will keep you out of trouble in a case like this. The meter movement actually requires a minute amount of current to magnetically move the needle.

RE: Help / Stranded / RV will not start /Road Service is no help

Different coach but mine has a similar panel hidden with a plastic cover. It is not in my battery compartment. It would be very close to the starter in order to keep the wires as short as possible. Once you find the relay you should be able to solve the problem in about two voltage measurements. Do yourself a favor and once you find it don't tug and pull on things to see if anything is loose. Takes some voltage measurements in case it is just a loose connection. Then you will have some facts. Better yet, take a digital picture and print it out. Then write on the picture your readings. Keep for future use. Don't rely on your memory.

RE: Can't enter Safe Mode

Password reset program Ok, if you can't get to the original disks this program should help. If there is not important data you could install a new system.

RE: Chasing electrical gremlins - GFCI outlet puzzle

I would bet a beer on a new one fixing the problem. I have seen plenty of them go up in smoke. Do try the voltmeter across a battery trick for a real learning experience. Not enough current to even feel but enough to drive a digital voltmeter. I have an old Simpson 260 analog meter that solves that issue when any doubts come up.

RE: Where did you get your Electrical knowledge?

Just basic electronics as a missile tech the Air Force more than thirty years ago. I've forgotten a lot over the years but I get by. I was stationed at Vandenberg AFB dealing with communications. It was fun to listen to the countdowns on our equipment and then run outside to watch the launch.

RE: electrical problem

Do I understand that you changed one of the two 6 volt batteries? Tested as in used a hydrometer and a load tester? If they did test correctly I too would recommend a Progressive Dynamics unit.

RE: Where did you get your Electrical knowledge?

Four Semesters of Electronics in High School and 1 semester at Santa Barbara City college at the same time taking the HS courses. Worked in TV shop for 9 months and took a correspondence course. Joined AF and went through more training. Earned the FCC commercial two way First class license. Senior Certified Electronic Tech Worked for Motorola Communications and Electronics for 17 years. From beginning technician to Senior Service Center Manager. Training many techs and ultimately responsible if they were not able to troubleshoot. Vehicle two way radio systems and of course all kinds of public safety equipment. Lights, sirens, cameras, Communications centers, relay sites, military communications. Component level troubleshooting. Have changed thousands of transistors etc. Today it is board swap, program, and throw away. After 17 years Motorola sold me one of their Service Centers. Have owned that over 18 years now. Doing the same types of things. Of course the technology has changed over the years. Helping technicians over the phone for 40 years really helps getting to the heart of the problems. During those years we have owned many RV’s. From very basic to the current techno monster in a 2008 DP.

RE: electrical problem

More symptoms before throwing the baby out with the bath water. How are you determining it is not working? Is it dead or just weak. What items are you running? What condition is your battery bank? Have the terminals been removed and cleaned and the ground connections cleaned? Have you tightened the wires at the converter?

RE: Chasing electrical gremlins - GFCI outlet puzzle

Your digital voltmeter was measuring a minute amount of current, enough to make the meter run but not enough to run a light bulb. With the GFCI bad there could be internal carbon traces or even a high valued resistor that does some sensing that is now feeding back power. If you had left the light in the ON position there would have been a load on the line and your measurement would have been zero volts. To demonstrate my theory, put the meter in the DC volts position and go to one of your 12 volt batteries. You could do this with a flashlight battery too. Place one of the negative leads of the probe on one post of the battery. Now with one hand pinch the other lead. With your free hand, touch the other post of the battery. By pinching harder or wetting your fingers you will get the full battery voltage showing. I promise you there will be no shock or any sensation at all.

RE: Can't enter Safe Mode

Some computers want F2 or F10. Give those a shot. I have seen them use the Del key as well. If you have the original disks it may boot from those.

RE: Help / Stranded / RV will not start /Road Service is no help

Very often a person will not share every detail of a problem. Not intentionally, they either don't think it is important or just forgot. For example in a recent similar issue a person did not mention checking their oil. Seems they managed to bump the rear start selector switch and things went on for a couple of days before discovering the issue. Working in the Electronic Service business and gathering information from the customer I tell them we are going to play "20 questions". Explaining they may think the same question is being asked again. Sometimes it is and reading the customers face is enough to show some doubt. Often the questions will elicit a bit of a different answer. And in some cases, the hidden clue is revealed by accident thinking the symptom was not important. This is why keeping the customer or officer around for a bit was always helpful. Even if the niggling intermittent was not showing up the clues often led to a repair. The OP had an intermittent problem in the beginning which would not be a blown fuse but could easily be a corroded one. It could be blown now of course. IF the OP can hear the relays clicking he should be able to locate them. If not, another pair of ears and eyes can help. I really suspect he will find his panel in the same condition as the one with the nicely rebuilt panel.

RE: Wholesale Warranty extended service agreement

I bought a contract with them just before going full time two years ago. No shop and limited tools along with major problem coverage it just made sense. I used the policy for the first time this month because my Voyage rear view monitor was acting up. Taking the information to a local RV facility they had a brand new one in a couple of weeks. The invoice was almost $800. It cost me $178. Not sure how that worked because my deductible is only $100 but it must be new math. In any case I am very pleased with how easy it was to use. I made no contact with the contract company, the rv place took care of everything.

RE: Help / Stranded / RV will not start /Road Service is no help

Since you have made your way to the rear following the ignition control voltage and you seem to be hearing the solenoids click and the voltage across the large terminals that you are within a few feet of the fault. At some point you need to sharpen one end of the probe on the meter or use one of those plastic headed thumb tacks to pierce the cable beyond the solenoids. What you really need is a schematic. Those solenoids you are testing may not have anything to do with the starting system or could be things like a grid heater control. Since you can control the starting solenoid by adding your own wires you know that part of the circuit is ok. Again, seems you are but a few feet from the problem. It is near impossible to physically follow some wires. The use of a camera can help enlighten things with flash pictures in places you can't stretch your neck or body. No days a go pro on a stick would be a great tool.

RE: Help / Stranded / RV will not start /Road Service is no help

fox and hound The way they hide things it is amazing how we ever get these things on the road. Just tracking down a blown fuse can be a nightmare. I have a panel with a couple of solenoids and breakers they you would never know they are there. Using some version of the Fox and Hound you can put an electrical tone on the starter solenoid wire and then sniff out where the wire leads to which likely will be another solenoid. While on the road I could not find a blown fuse and had to install a temporary patch. Once home the Fox and Hound traced it in a couple of minutes. I will never leave home again without it.

RE: How does a macerator toilet work?

Make sure no paper other than tp is ever flushed. We have been using ours since new in 2008 and it has never clogged. Check your manual for programming the buttons. I can set the water level on mine and can flush with little water or normal water.

RE: Battery isolator

Newer vehicles already have a relay. Some need to have a fuse installed to activate them. Check the manual. In regards to a relay, Fords do, GM and (thankfully) Dodge/Ram don't. What ? Where is your expertise and can you explain. Sorry, 40 years in the industry begs for a clear and concise answer.
