Sorting out the PO & Renegade's ... interesting wiring and I'm looking at the ground path.
Starting at the battery negative terminal, there's a cable runs to the back of the alternator pivot bolt (not to the chassis), then there's the transaxle ground cable away back at the back end of things. I'm fairly sure that this is part of why I am only seeing 10V at the dash with fans and headlights on (lots of ground path resistance). Where was the battery ground originally connected? Worst case I can just run another 2ga cable down to the transaxle ground, but that seems a bit silly. If I can, I'd like to find a well-grounded bolt nearer the battery... Thanks for any suggestions. I think a 105A alternator is also in my near future. |

The majority of the electrical system uses the body as ground.
This is why the battery is attached to the body and not the motor. If you are having starter issues, fix the starter or get a new tranny ground strap. If your alternator is not charging properly, fix that. I ran an extra ground wire to the starter bolt, that worked for me, but I left the ground attached to the body. Everything aside from the starter and the fuel injectors is grounded to the body. The lug is right next to the negative terminal, on the inner fender, can't see it unless you look up under the sheet metal deck lid shaped piece. |
