Well, the alt was dead, and thanks to the powersteering pump, my old one didn't fit. So I got one from a scrap yard. Installed it, charged the battery, and everything seemed fine. Then the battery died again. So I took the alt back (figuring it was a dud) and got another one. Installed it, charged the battery,and everything seemed fine. Well, on the way to work this morning, I noticed the tacho flicking. First reflex, I turned off everything pulling juice (the radio) and didn't I hear something coming from the speakers still. A whistle. A whistle that varied pitch WRT the RPMs. Damn, Damn, Damn. Looks like I've got a ground out somewhere. Damn, Damn, Damn.
BTW she got me to work before dying again.
