RE: Samplex 450 msw inverter noise
Yes. Get rid of that junk and buy pure sine wave inverter.

RE: PRNDL Indicator repair
The repair should be very simple. As you move shifter handle, the gear indicator moves with it. The string either broke or slipped of cam or something like that. I have a factory manual for 2002 F53. If you need anything specific, let me know. Take a good look under the steering wheel.

RE: Open Ground when on PSW Inverter -- Experts please advise
One of my junk inverters collecting dust in basement actually has voltage at the ground prong at the output. This voltage is about half of the voltage between the two power prongs. So if you are connected to shore power and you plug any three wire appliance into the inverter, you could get shock by touching the appliance with one hand and touching any other appliance like fridge for example that is grounded thru shore power cord. This clearly is a safety issue and I don't want inverter like that in my RV.

RE: The best photovoltaic solar panels
BFL13:
Perhaps this will help: Lets say you are charging batteries at 10A and at 14V with a charger pluged into 120V outlet. How much current will flow from the outlet at 120V?
10Ax14V=140W...140W:120V=1.17A.....so 1.7A at the input creates 10A at the output.
Now lets say you plug your battery charger into a 36V outlet. How much current will flow from the 36V outlet to produce same 10A at the output?
10Ax14V=140W...140W:36V=3.89A.....so 3.89A at the input creates 10A at the output.
If 36V and 3.89A were Vmp and Imp of the solar panel, with MPPT controller you would create charging current of 10A at 14V. With PWM controller you would get only 3.89A of charging current.
(Assuming 100% efficiency of conversion for clarity).
Panel efficiency:
Lets say you solar panel is exactly 1 square meter big. If this panel is illuminated with sun light of 1000W per square meter intensity, your panel will convert it into 1000W of electrical power, right? Wrong. All you will get is maybe 120W to 160W:
Efficiency = 120W:1000W x 100= 12%
160W:1000W x 100= 16%

RE: Open Ground when on PSW Inverter -- Experts please advise
Incorrect. The tester works just fine. What user may not realise is that the ground prong of these inverter's outlet has voltage with respect to ground. This defies the purpose of the ground prong which is suppose to connect the outer shell of the appliance to the ground potential to prevent electrocution. So if your RV happens to be connected to shore power thru shore power cable and you use inverter you might be electrocuted. It is best to avoid inverters like that especially when better inverters are available.

RE: Violent shaking front end
Aside from worn componets on steering axle, this is ususally caused by too long leaf springs that allow side to side movement of the axle. The solution is either steering stabilizer(a shock absorber) or track bar or both. An other check worth doing is check the caster angle.

RE: Misleading avertising/ignorant sales people
Like most capacity ratings the rating is determined by the weakest component. When it comes to tow rating, it could be limited by hitch rating, drive train rating or frame construction. Sales people take advantage of peoples limited knowledge all the time.

RE: Open Ground when on PSW Inverter -- Experts please advise
It is normal only with junk inverters. There are inverters that will make your tester light up exactly same as shore power. Like Xantrex Prowatt SW 600, 1000 or 2000. This has very serious implications when you want to wire your inverter into electrical system with transfer switches.

RE: 460 exhaust manifolds
It should be clear to you popeye766 more than anyone else that replacing gaskets is no way to solve the problem. The problem with stock manifolds is the front end of the manifold receives heat from one cylinder only while the rear end of the manifold receives heat from 4 or 5 cylinders depending on engine.This causes unequal heat expansion(and warping) of ends of stock manifolds. Tubular headers are the only answer because with headers each cylinder has its own header pipe and heat load is more or less equal for all cylinders. This applies to both 460 and V10 engines.

RE: K&N Filters
I have K&N filters in a car, SUV, pick-up truck, motorhome and a boat. I sold 1984 Jeep Cherokee and 1991 Nissan Sentra, both with over 300000km on the odo that ran like new when sold. I bought my first K&N filter in 1975 and buy them for every vehicle I own ever since. My experience with these filters indicate that there is absolutely nothing wrong with them. If paper filters work better for you then use them. I am not throwing any of my K&N filters away.

RE: Where is power inserter on King Dome?
My KD 9762 has a separate power supply, similar to laptop brick. That plugs into the separate tuner from where the power goes to dome thru coaxial cable. Check page 2 of the manual

RE: 460 exhaust manifolds
2013 JBA Headers Catalog
The brand is JBA. I got them from a local distributor in year 2000. It appears that that part number is not in catalog anymore. I would contact JBA to see if they are still available or if they would make it for you.

RE: 460 exhaust manifolds
The part numbers I installed in 2000 on my 1989 class C w/460 engine are:
JBA J1629JB -headers 88-98 Ford truck 460 engine
JBA J1629Y -Y-pipe Ford truck 460 EFI
They had black ceramic coating advertized good for 2000 deg. The only modification I remember doing was straightening the cross shaft for transmission shifter to clear headers. The Y-pipe bolted directly to the catalytic converter. I sold that motorhome in 2002. No exhaust manifold problems after the header installation.

RE: How many miles on your Ford V-10, and what problems?
2002 F53.
-at less than 20000km: rear axle noise-axle rebuilt under warranty
-at less than 20000km: transmission clutch failed-transmission rebuilt under warranty
-at around 25000km: two exhaust manifold studs on right side broken
-at around 36000km: right rear caliper pads uneven wear-replaced
-at around 72000km: same thing, replaced on the road-carry spare since first occurence
-at around 75000km: transmission cooler leak-must be replaced
This chassis is good compared to the 1989 E350 class C I had before. Absolute POS. First five years of ownership I could not leave driveway without fixing something first.

RE: Please explain battery AH rating
225Ah@20h:
The average discharge current for 20h will bring battery voltage from fully charged to 10.5V. For 225Ah@20h that average current would be 11.25A.
185Ah@5h:
The average discharge current for 5h will bring battery voltage from fully charged to 10.5V. For 185Ah@5h that average current would be 37A.
Higher the discharge current, less capacity the battery will have(Peukert effect). That said, for maximum life of the battery the battery should not be discharged more than 50% of the battery capacity.
So at 11.25A discharge current that would be 10 hours, or 2.5 hours at 37A discharge current.

RE: Radio clipping peak sounds
Remember that the maximum power your 12V radio can deliver into the speakers is limited by the supply voltage squared divided by speaker impedance. So the supply voltage drop is definitely a factor and speaker wiring resistance does not help either.You might prefer to run home stereo thru inverter like I do for super clean sound.
