#193 of 197 electrical surge problem-1994 ford mustang GT v8 by mustang94

I have a ford mustang with a major electrical problem ever since I was cut off and rear ended a car knocking down my whole bumper, and messing up a headlight, I had them replaced and the bumper bent back up into place, and the passenger side window motor replaced. And now my car while driving over charges it self in surges, very high electrical surges making my heater and lights much stronger and cutting off my radio eventually blowing out my alternator and a 30 fuse, we have replaced both of those twice thinking it was the alternator but it must be something else. Also when I turn left or hit bumps my dome light flashes on. And there is air from my engine coming in through my defrost and below my dash while driving that smells like oil not radiator, and the vacuum hoses are all good.. Please help me with these mysteries..!!!! It's a 1994 GT FORD MUSTANG V8.

Has anyone load-tested your battery and also checked the battery for a large parasitic drain?

I have had the same problem with my 07 mustang water starting leaking from under glove box/ SJB area since 2011. We have had major electrcal issues and my car will no longer start and have replaced two batteries in one year. My car is currently out of service and won't even turn over. What can I do to get Ford's attention in this matter , the local dealership wants us to pay for service. We do not have the funds to dish out on this vehicle that is not even paid off yet. Any ideas???

Check the passenger side floor to see if its damp. Chances are that your fuse box which is located on the wall between your windshield and passenger window is corroded. In addition check if your interior air filter looks wet/damp/moldy or dirty which indicates you had a leak. First part of the remedy is to remove the panels below your windshield wipers as the drai holes is probally block with debris. What happens next is this: Water fills up as it cant drain,then enters into your interior air filter box which in turn water drips or runs downwards the wall into your fuse box thus corroding the contacts. You now have 2 choices if this is the case,try to clean the contact points yourself with an extremely small brush as you have to scrape the corrosion off. Second choice is to find a repair clinic and replace the fuse box(most likely you'll have to do this) Cost of box and labor is about 700.00 Try a dealer and it may cost you about 2 grand. Do NOT let someone replace the fuse box under your hood,that is NOT where the problem is. Its going to be the fuse/brain box on the wall next to your passenger door. Good luck

Thanks for the info. We pulled the carpet loose and our SJB has major corrosion. Since my leak started after my warranty was expired the dealership won't repair without us forking the bill. We cleaned the SJB and it did start but it is still having electrical shorts with radio and lights. I have recently contacted BBB to take this further since our car is under 7 years old and is considered a lemon because of major water damage. Even if we wanted to trade it in we couldn't because it reaks and major damagg has been done.
