a long time ex-girlfriend said her dad used to do that when she was a kid if she ever hit the hazard button on the dash, lol!
Buttttttt. New alt arrived and looked like it had already been installed by somebody. greasy hand prints, grease on the mounting foot.
Either way, i installed it. Got it in and all tightened up. seems to be slightly more misaligned than the last one, but i can tweak that.
Tested good, 14.5v at the alternator during idle, 14.4 at the battery.
I again tested for a poor ground by checking between the alternator body and the negative battery terminal. It showed -0.03 volts, so there is a voltage differential of .03 which is way smaller than they say to watch out for.
I revved it up to 1500 rpm and had high beams, AC fan, heater fan all on high and checked, it was -0.05v at the negative terminal, and -0.08v between the body or the radiator, etc. So, again, still under .1v.
We'll see how long it lasts....
