fuse question

[Wartburg]

I have a 1985 CUCV M1008 and have been having a hard time running down wiring problems (the last two owners have altered some of the wiring). I found the on line manual and on page 4-13 there is another fuse block for a m1010. Do I have the same fuse block on my M1008? and if so where the hell is it? I had the dash all the way out last night and climbed under the front in but can not find it.
Someone had put a radio in the truck at one point and ran a jumper of the negative number 2 battery. I believe you are supposed to use the number one positive?
My volt meter on the dash does not showing charge now, BUT IT DID BEFORE. and one of my alternater lights does not come on when the key is turned on. I have been looking at the manual for about a week and running around with a test meter but can't find this grimlin. SORRY TO BOTHER YOU GUYS WITH SOMETHING THAT IS PROBLY SIMPLE FOR YOU.
THANKS ,

The -(neg) on the rear battery is connected to the +(pos) of the front battery, so that was ok(12V).
Is it your gen 2 light that is out? When you say the volt meter does not show a charge, is it working at all(indicating voltage)? If it does not read at all, it sounds like you either have a fuse bad or the gen 2/voltmeter relay is bad.

Does the Wait light and Water in Fuel light work? If not, check the fuse marked IGN under the dash.

It is my Gen 2 light.

The voltage meter is not working at all. Is there a way to test the voltmeter relay?

Check the fuse at the very bottom of your fuse box, it says 24V . It should be a 10 amp.

I will change the IGN Fuse this weekend, and see if that is it.

Does anyone know anything about another fuse box on the truck? I found a pick of one for a m1010 but can not find one on my truck.

Thanks guys for all the help.

The M1010 is the ambulance and it's second fuse block is in the ambulance body in the back under the driver side bench.

Your wait light and water in fuel light probably has nothing to do with your current problem. There is a picture of the fuse panel in the 9-2320-289-20, page 4-31 also step by step repair and identification of the gen2 relay and voltmeter relay Page 2-59.

Did you look at the red 10 amp fuse at the bottom of the fuse panel? It is probably blown. This is not the ign fuse.

I pulled most fuses one at a time and then replaced them looking for a bad one but I might have missed on. I will double check it after I get back from the state wrestling Tournament tomorrow night or first thing Sat morning.
Thanks for all the info again. I will let you know if the lower 24v and what ever the 10v fuse are help me fix it.

If you click on the Resources link at the top of the page and then select Technical Manuals, you can locate and download the CUCV manuals from this site. You are looking for the 9-2320-289 series of manuals.

Here is a direct link to the -20 unit maintenance manual.
