48 cj2a grounding questions

Post by 42GPW » Tue Nov 21, 2017 7:28 pm

Okay I have a 1948 cj2a. 12 volt. I cannot find any information on all the grounding locations. But when I go to images I see where guys have grounded everything including the muffler pipe, to the fuel lines. I do not want to go to that extent. What are the major areas that I need to ground? i e, engine ,chassis, body, Etc

The only reference to grounding is the engine ground strap from the frame using the bolt that holds the motor mount to a bolt through the mounting plate under the generator/alternator and of course the battery ground to the frame. I think some of the other grounding everything was from mb/gpw because of radios in them for interference. The other grounding lights and gauges etc just get to the body or frame

Just to be sure, I put a ground wire to the body and one to the frame on Ol' Unreliable. I figured it couldn't hurt. This Jeep is neither original nor restored, I just want to make sure things work.
Is it true real Jeeps have flat fenders?

1. Battery to frame
2. Frame to engine [engine mounts are insulators]
3. Frame & engine to body.
Make sure all are dimensionally correct for max current they will be required carry.

Understand how system parts interact with one another. GOOD parts can then be established & the NOT GOOD problem/s part/s isolated for repair or replacement.
