Electrical questions

[Armywelder]

Hey guys im new to the forum so bear with me. I bought my cucv about 2 years ago already converted to 12v. It has been a complete electrical and starting nightmare since. After many burned up starters and altenators I think I might of got it right. Due to my front fender rotting away I moved the batteries to the back and connected them to the bus bars that are near the passenger side rear seat. Positive connect to positive then to the bar and negative conected to negative then to the bar. It works but doesnt seem to be getting the full juice it should. Is this a safe setup and if so what might be the problem? Think each battery is 800 or 1000 cca.

Putting batteries inside the cabin is a bad idea.

Without more info on how it is wired we are just guessing. Need pics, description, etc.

It also helps to tell us what truck you are working on. Since you said rear passenger seat, we can assume it is a M1009

Yes it is an m1009. I will take some pictures of the setup tomorrow. I know its not the best idea for batteries inside the truck but with the way its rotting out it either that or risk having a battery fall out while driving.

Yes I know the fact that I didnt use red for positive and black for negative is going to piss someone off, its all I had for now. If it works I will match color. But basically its positive connected to the positive then connected to the top bus bar and negative connected to negative then to the lower bus bar

Here is the under hood situation

looks like that has been hot , maybe a bare spot under it, also have you tried each battery by itself, a bad cell maybe

This is a real safety issue. If you put them in cab, they should be secured and in a battery box of some kind. It would be best if it was vented outside cab. Ever get a lungful of acid fumes? Not to mention shorts, acid burns and fires if there is an accident.

I'm with dependable on this. A real bad idea. Repair the wheel well and battery trays and put them back under the hood.

You need the ground going directly to the block and the pos should go straight to the starter relay . Your creating resistance the way you have it wired , it will continue to eat altenators and starters ,

I work in a sheetmetal shop so making a box isnt a problem. Should I move it closer to the rear? I dont own a welder so replacing that fender is out of the question for now... this just needs to get me through the wicked winter. So where is the starter relay?

Those inner fenders are available new, pretty cheep, from Mill Supply. You might add the reenforcements for the battery mounts from the old one.
