Stu,
If you're interested, I'm finishing up the discussion we had a while back about oscillating voltage in my Tempo, only b/c it's similar to the
4-cyl Mustangs...It uses a 75A "Mitsubishi alternator". It's a v-belted one. Stick + air apparently required a different alt. than auto + air. Ok..
The charge lead plug is apparently notorious for corroding and shorting. It was horribly corroded, and replaced it and the alt., and had recently replaced the battery, leads, starter solenoid while I was at it and terminals of course because it "puked".
The reason it "puked" was, from what I've put together and heard, because of the bad plug from the charge leads. The voltage going up and down violently enough for long enough fried the alt. and, as I thought back, caused two batteries to puke and two alternators to cook in 80,000 miles.
Fried alternator with battery puke sounds like a tasty dish, but it was expensive, frustrating nonsense. Finding the friendly neighborhood parts store instead of the know-nothing chain, where no reality exists outside their computer screens, saved me from having to go through this b.s. again with my beater. Hey, I know what I know and don't what I don't. I'm ok, but not great with diagnosing electrical problems. I should have looked for corrosion before, but didn't...
If this information is valuable to anyone, then good deal... that's why I bothered to post it... and thanks for the help on the other stuff, Stu...
