Customer Question

I'm a heavy equipment mechanic helping a friend on his (1993 jeep grand Cherokee Laredo with V8) the vehicle has had electrical problems since he bought it 5 years ago. the engine computer was replaced 2 years ago and again 1 month ago along with the throttle positioning sensor. I looked at the vehicle for the first time today it will start up ok but if you put any electrical load on it the engine starts to run rough until you put such a load on it the engine dies with a fully charged battery I ran temporary ground cables to the engine and body and the problem went away even after I pulled temp. ground cables off have no idea why just a coincident or motor hit a certain temp. I have no clue

Hello, my name is***** the temporary grounds helped that would mean you have a ground problem You will need to clean battery cable grounds and any other grounds you see. If problem still exists then run new additional grounds. Let me know how it goes or if you have more questions, thanks.
