I have physically disconected the batteries and pluged it in to shore power I have 12+ volts comming out of the two big wires and the same on the other side of the fuses. but some how it is not going to the batteries. I traced the wires comming out of the fuse box out under the coach and the go the booster switch and seperate and go foward to the cab.


Alan.

I sure wish you could send me a picture of what you are talking about I just spent an hour on my back underneath looking and never saw anthing like it.

I am open for more suggestions ??
Paul

Normally the 12vdc to the batteries and the univolt feed all run thru the same screw lug on the fuse block. The only thing I can think of is that there is a fuse, an open, or cutout switch between the batteries and the fuse panel. I would start by, with the univolt on, testing each connection from the panel towards the battery unit you find one without power. Then you know the last connection you tested was the bad one. It could be as simple as a connector with unseen corrosion.

im confused .
1.you have lights when the batteries are charged and hooked up.
and you see the batteries at the fuse panel.
2. you disconnect the batteries,connect ac power and your charger humms and you measure 12 vdc at the fuses. you should see 14 vdc not 12 . could someone verify this step. 12 vdc wont charge the batteruys but it would hold them at 12 vdc not a complete charge.
3. gotta be the ground. can you run a temporaty ground from the batteries to the fuse that is connected to ground?? the ground on my unit is a solid 10 awg wire and it goes to the frame thru a aluminum lug. how cheap can you get aitstream . i plan to change that lug to copper some day. that is a corrosion point and problrm area if you have the same. dont mess with the pile of what ever on the rear of the battery drawer. just yet, you will hurt your wallet fast. lol

Paul,
check if you still have the 12v+ at the fuse box without
1. shore power
2. coach batteries connected

If you do, you have a bad battery isolator and a bad converter

I have found two grounds one comming from the converter to the frame and one from the batteries to the frame both seemed good and tight. Still no lights inside while hooked up to shore power. Are there any fuses under the dash I should look at? I checked to see if any were bad they looked good.

(George is getting angry) that is from Sienfeld if you did not know!!!

Paul.

no fuses i know of in the dash.
peter
the isolator isolates the coach batterys from the motor battery . just dont agree but that dont mean im right. been known to be wrong. but not often on electrical problems.
paul
i dont know what to tell you to look at next. but i will be at the fair grounds in nashville saturday and sunday . bring it over and ill give it a once over. i have an ole miss rebels plate on the front bumper. i hope to park on the upper level if not ill be down at street level. lol

Al, my point about the isolator is to eliminate multiple electr. problems, which make it hard to trouble shoot the real source.
I would physically disconnect the converter wires from the fuse panel, connect the coach batteries (or start the engine) and then read voltage on ALL of the fuses in the 12V distribution panel.

dont know if you remember my marker light problem. i could read 12 vdc on the wire but lights wouldnt light. problem was a corroded connector. i had voltage but not current. i think the fuse block could be bad but he says he measures 12vdc on the converter leads which is low should be 14vdc . that would indicate a bad converter. but someone should check to see if that is a true assumption before spending bucks. lol

On the two 50 amp fuses, the top one on the right I went to make sure it was tight and the whole side of the fuse clip moved when I tried to turn the screw to tighten it. But I still have power coming out of the side, if it is a bad clip would it not have voltage?

Paul.

Okay here is the latest the converter is D.O. A. Nothing nada nunca. zero power.
The converter is not a univolt. So how do I fix it. The next step will be to take it out and figure out what is wrong with it. What is the cost of a new one?

Paul, I like the lightweight, quiet
Intellipower
It has a charge wizard that comes in handy at times (i.e. when dry camping you can boost the charge during generator usage).
Also, you may want to consider running a wire thru the firewall to the isolator (coach battery side) and install a volt meter in your dash.

Al,
yes, I remember your marker light problems and I always enjoy your follow up and solutions of problems you encounter.
The collective brain is what makes this place so valuable.

The intellapower looks like it would do the job. Where con I look at one and what size do I need. You know size does matter.

i have the intella power unit installed in my coach. come buy sunday and ill give you a tour. ill show you how to fix the fifty amp fuse problem. that fuse strip cost 70 or 80 dollars. i couldnt belive it. i did something else but wish i hadnt. jumped off the deep end on that fix. but it works .
well peter
i think any one who has helped deserves to know the problem and what the fix was. you see the same problems over and over. and i have had a lot of help. and ive had to look back at some of my post and ask myself what was i thinking when i did that. it is a dificult task to relate to some one you dont know what their skill level is. but i think we have fixed a large number of problems. dont think im rude an crude im just not a english major. thnx to all
