aerolithe

Looking for help and idea
I got a 1986 base with some electrical issues. I clean all ground (I beleive) My blower, front and rea rwipers, reverse light and fog light dont work. If I apply power to the blower motor and wiper they works, I check the switch for reverse light at the transmission and it work test the light and ground at the rear assembly and they work.
If I apply 12 volts on the swicth. I found the big red cable damage on the rectangular plug O under the fuse box repair it and no go. At the battery terminal we have multiple of red Cables who connect there where do they go?
Any more place to check ?

Do you have a voltohm meter? If not, purchase an electronic one, Craftsman is reliable and less expensive than commerical/ industrial grade like Flute. Craftsman sold at Lowes
For each device to test, remove the ground and power connection. Test for continuity on the ground wire with the meter on resistance between the ground wire and solid clean ground on the chassis with the probes. Test the 12v power supply connection with the meter set on dc volts, red probe in 12v connection and black probe to good chassis to ground to determine voltage.

There are multiple ground points on the chassis. Go to Pelican Parts for electrical schematics and also other schematics available free on the Internet

I did check continuity for ground and it work. If I put 12 volts direct to the unit it all work. So my ground is OK
The red cable who leave the connector (0) that the one I try to track down
Any Idea ?

No I do not have 12 volts at the unit
Do you know where I could find diagram of the fuse box with cable identification for each cable
