does it work when you initially start her up, but then slowly dies off?

I had an issue maybe 4 days ago with my alt. worked great in the morning at initial startup, but after maybe 5 miles voltage dropped to 12-12.5 (ie: battery voltage).

had to take in for testing while burning hot before it would "fail" the test at Oreilleys. $218 later and I have a lifetime warrantied alt...and a new battery because it killed the old suspect one that was previously there. get it fixed soon before it kills your new batteries.


not to mention that your FICM HATES low voltage and it can kill the FICM and injectors
