Upgrading Alternator and Cables
I am most of the way through swapping in an upgraded Durango alternator and new upgraded cables. I am running into a few problems keeping me from wrapping things up. I am new to electrical and trying to learn so I am hoping someone can help me ensure I don't unintentionally set my jeep on fire or something.
1. The original plastic cover for the Alternator stud doesn't fit with the larger alternator and gauge wire. Is this needed and if so, what suggestions are there? 2. My battery ground bolt snapped withe tiniest bit of pressure when I started. I know I can just sand down the paint to bare metal on the frame and put a new bolt. I don't know the best type of bolt to use for this (bolt and nut, washers, self taping, etc.) to ensure a solid mount that wont come loose and provide good connectivity. 3. The engine bolt on the braided ground to firewall is difficult to access on my 99. The cables that run on top wont budge and I can't get the appropriate sized deep socket in there to remove. I tried an open ended wrench and got a little turn but it won't turn further due to hitting the valve cover. Any tips? How do people get this out? Remove all the wiring? Any help or suggestions with these items would be great. Almost ready to start my jeep up again. I have been reading lots of old posts to get to this point and these are the answers I haven't been able to find yet. |
rear head bolt
while doing a number of under hood jobs,driling/cutting, i cut a 4 inch piece of the flat firewall metal blocking access to that bolt for future access. i cut it with a air tool cutting wheel. access no longer denied!!
i wouldnt worry about the plastic cover. 2. good bolt with a couple toothed lock washers |

It's not a good idea to leave it unprotected. I suggest you at least paint it with some liquid electrical tape. Better yet, try to find some kind of rubber boot that will cover it.

If you can get a Dremel type tool in back to clean off the paint around the hole on that side, that's even better. I don't have one, so I passed on that.

If it's corroded, you can just cut if off neatly, get a longer braided ground strap from the auto parts store, and connect it to the firewall location and then to any convenient bolt on the intake manifold. I know the forum members that sell the upgrade kits push those, and I'm sure they mean well, but that part of the "upgrade" is just a huge blunder. It's not a good thing. |
Thank you both. These ideas are helpful.
Also glad to hear some reinforcement on the firewall ground, I saw that posted somewhere but most threads didn't mention the drawbacks. Should the ground bolts be any type of material? I will probably head to a hardware store in the morning. |
Nothing special needed. You can use ordinary cad plated bolts. Stainless steel if you want to get fancy. Since it's a one-off, that's not expensive.

Hmmm. Thought so. It was bugging me, tickling at the back of my brain, so I came back and looked at what I posted. That's not what I did (though it would work). I put the bolt through the back, then a flat washer, then a nut, and tightened it all down. Now I have a stud sticking out of the fenderwell which will accept the ring terminal from the battery cable. So, next (after the nut), is another flat washer, then the ring terminal, another flat washer, and a final nut. Now you can disconnect the cable without disturbing the ground stud. I'll try to remember to get a picture of it for you.... |
Thanks everyone.
