I just recently bought a 1990 keep Cherokee limited 4.0. I am having a bit of an electrical issue. When I start my rig it runs fine. Starts up as it should. Getting the power as I should. When I switch on lights or turn on the heater or any dash components my dash guage drops from 14 down to about 12.5. If run it it then eventually dies when I slow down and stop, but will start right back up a little bit later. During this time it seems to run a bit warm, not much but warmer and it starts running rough. I've replaced the alternator and battery and test both with a digital multimeter when it dies from loss of power but both readvery good. I'm going to clean me grounds today but need more guidance as to what to do. Please help.

 

This is a renix XJ... Clean every ground

 

Clean grounds, check battery terminal clamps. That's how I'd start.

 

Gentlemen, thank you for the responses. I will let you know how it goes.

Figure anything out yet bud?

 

Been working crappy hours at work. haven't had a chance to clean any of my grounds yet. Going to wake up early tomorrow and check them all out. Worse comes to worse I ride my crotch rocket into work. Hoping it is dirty grounds. i don't want to waste too much money fixing something I'm going to start upgrading real soon.
