'95 Mystique V6 5 speed. 300,319 miles. In great shape, garaged from new until 2007... only to make room for my 2004 Cadillac CTS, V6, 5 speed.
Alternator was whining for last 3 years, since 240,000 miles. Battery was always being charged, and no warning lights, so I kept driving with the whine.
Last week, battery dashboard light illuminated. I figured alternator finally went. Drove home and parked car.
Took out alternator. (What a •••••). Had it tested. NG. Bought new remanufactured, and installed.
Started car. Battery dashboard light was not illuminated, so I was initially happy, but the battery was not charging. 11.8 volts across battery when engine running. 12.2 volts engine off. The battery dashboard light did not illuminate either with key in ON/accessory position, or with the car running !!!
Found 175 amp Mega fuse blown. Replaced it. Checked for continuity between cable at the alternator before the megafuse, and the positive battery cable after the megafuse. I had continuity. Good, I thought.
Turned key to ON/accessory position. No illumination of battery dashboard light.....
Started car. No illumination of dashboard light..... Still no charging of the battery. 11.8 volts with car running. 12.2 volts engine off.
Disconnected the battery and the cable from alternator. No more continuity between alternator cable and battery cable.
I want to keep this car.
Does anybody have any ideas?
Cables look good, no worn insulation, but I still need to trace the positive battery cable and inspect it throughout its entire length. Negative cable looks good, and looks good to ground.
Battery is only 2 years old, and is holding a 12.2 volt charge, cables disconnected.
Any ideas, please.
I'd hate for my next step to be posting pictures in an attempt to part-out the car.....
