Hello all! Looking for some information on an issue that I am having.


I used this tutorial to start on my battery cables and such, but did a run down of looking at all the places for wires first. I got to Number 3, the Engine Block Grounding area with 2 bolts. This tutorial says the right bolt is the ground, however, mine had 2 wires crimped to a single connector on that bolt, with no ground. The left bolt looks exactly the same as the picture.


First, what are these 2 wires, crimped to one circle connector on the right bolt? Secondly, I took the bolt off, and tried to re-thread it back in to no avail, and had issues (reaching) to get it in deeper, are the threads deeper? Third, the connector broke off with 1/4 turn of the bolt. Anyone got any suggestions on what these wires are and how to fix?


I assume they are to be grounded, so would splicing these to another wire and run them to the fender ground work, or is that a no-no? Very on edge and really, REALLY frustrated at what happened and how to fix our (was) only running vehicle.


The tutorial I followed is below:

I found a picture someone else posted that fit the thing PERFECTLY.
The black circle is the wire I am talking about. The other wire I put red lines on is NOT there.

You'll see pics of the ground points in your '99 engine bay.

The one you have questions abut is G101. The pic shows what circuits are grounded there.

Both sets of wires need to be attached here, as well as the ground cable to the battery. These wires are not to be grounded at the fender.

 

Ill see what i can do to the one bolt, but as for the negative, i have no idea even where it is currently.

 

Sorry, but I have no idea what you are saying here.

 

In the initial post i am having issues putting the bolt back in, its incredibly rusty and not sure if there is threads in the block to hold it.

Any chance you know what size bolt that stud/bolt is?

 

There are normally 2 cables coming from the negative battery terminal.
The negative battery terminal is connected to the fender wall.
Can the car run if there is no cable that simultaneously connects the negative battery terminal to the engine block?

 

I take it you're talking about one of the coil mount studs. Couldn't find it in any parts catalog, but I do know that the end that does not go into the block is 5/16-18". The threaded end that goes ino the block is probably a coarser thread. Take the other stud bolt out and take it to a hardware store that has one of those bolt/nut thread sizers. Buy a bolt with the size and thread pitch that goes into the block. Lube the hole in the bolt with penetrating oil and see if you can work that bolt in and out until the threads are cleaned up.

Give it a try and get back.

 

Did you try wire brushing the stud? Or spraying some lube on it?
If you just took the nut off, I can't see how it doesn't thread back on.

 

The nut busted was so rusted on the stud that the entire bolt had to come out.

CC will try my hand at the other bolt, I'm afraid with the way this one went.

I've tried lube to everything, wire brush to the bolt and head..

 

A new bolt may do it OK, but if not, a 5/16-18 tap could be used to chase the threads to clean them out. There appears to be enough room to run a tap in there.....assuming the thread is that size when you check it.
A place that has the bolts may also have the tap...

 

Thank you steely, it's much appreciated. I'll try the tap first just to make site i have good thread in there, and won't have to go through this again.

 

Wait, so you tried to remove the ground bolt, and the stud snapped?
Welcome to the wonderfully rusty infuriating world of working on XJ's!!
