I added some extra grounds to a '96 Cherokee with 4.0 HO. I hadn't came across Cruiser54's tips yet, but I think maybe these pics might save somebody some time. less than $10, 20 minutes or less unless your tools are scattered Here we go let's start here:

Unhook the battery negative first.

 

Locate the the battery ground on engine. Its under the AC.


Battery ground on engine under AC

 

Here's a closer view. There is another ground immediately forward of the battery ground.

A closer look at two grounds.

 

Remove the nuts from both


denutted

 

Now strip and wrap a solid core 10 or 12 guage wire to connect these two grounds.

Wire smashed flat to hold shape and offer better connection

 

Now make your next connector from 10 guage wire


10 Guage 18 to 19 inches long

 

Crimp on the 3/8 stud eyelets


Eyelets crimped on both ends.

 

One end will go to the battery ground stud on engine. The other end will go behind distributor if equipped to the critical ground by the dipstick tube.


Clean the nuts, tighten everything back up.
Hook your battery back up, reset your clock. Happy motoring

 

So essentially, you're bonding the grounds more so than adding extra grounds, right?

 

Or you could cut off the old lugs and solder on some new copper ones for 6 AWG, and wire wheel the **** out of the block, because if you don't do any of that connecting the grounds wont help much.

 

That's what it looks like to me..

 

right! i never crimp solid wire, it always works loose.

 

Correct!
Solid wire should be always be soldered to the terminal.
Hell even with heavier gauge stranded, i crimp and then solder them too.

 

Did any thing get different after this ?
