OK, so i'm driving my mustang around(not even beating on it i might add) and all of a sudden BOOM! The entire car dies! When i say that i mean i lost everything electrical, car shutoff and i had no power to any accessories at all. Nothing, no hazard lights, headlights, windows, locks, radio nothing at all! NONE! So when i couldnt do anything i had i towed back home and started to look into it. I checked all the fuses inside the car and also under the hood fuses as well and none of them were blown. Battery terminals were good and tight so i got the test light out and was checking a few things and i had the light hooked to the negative terminal and just happened to check the ground wires that are connected to the rad support right by the battery( i think they go to your headlight harness) and they were hot! Like they were ground wires that were positive! So i checked them again and when i did it sparked and my whole car came back to life as if nothing happened, runs fine. I havent drove it yet thought jus put it back in the garage. I did notice that when the headlights/parking lights are on and you turn on something like a turn signal, the rest of the lights in the car will dim as well every time the turn signal blinks, which i thought was a ground issue. I do know that the headlight switch plug needs replaced. Its got a burnt spot on it hat seems to be so common for 94-04. Also when driving around with the lights on and when you go to step on the brakes you can hear a ticking noise coming from under the dash almost sounds like a relay kicking in and out. and it doesnt stop unless you let go of the brakes.(i replaced the headlight switch it didn't seem to help)




THIS IS WHAT I DID SO FAR TO TRY AND FIX IT!
I put new battery terminals on and made sure all the grounds i could find had clean bare metal to be mounted to(with electrical grease) . i checked the ground going from the battery to theblock, checked the starter wires and the alternator wires. I also added an extra 6gauge wire going from the passenger side motor mount to the sway bar mount.


PLEASE HELP WITH SUGGESTIONS/EXPERIENCES AS ANY LITTLE BIT WILL HELP! THANKS

yea the ground wires by the driver side headlight are always a culprit. make sure those are tight they do strip out so sometimes you have to combine the two . make sure you have a good ground from your battery to the frame

yea this def sucks. I'm kinda hoping the headlight switch harness is the culprit. Otherwise looks like i'll be tearing the whole car apart to put a new harness in.

I had a similar problem 2 years ago, im thinking mine might be either a ground or the alternator cable that has that oval rubber cap.
I replaced a ground cable it seemed to help some, as well as that alternator cable, but I still get similar problems like when I turn the on (stock stereo system with the Mach's in the back) turning on the lights, etc.
