Drove it to lunch yesterday and it was fine. Got in it to go home last night and the gauges were flashing "18V" and "Check engine". Pulled it back in the shop, hooked up the multimeter and sure enough, it was sending 19+ volts into the battery. Shut if off and unhooked the battery, I'll go get an alternator at lunch today
Nah, just smack the alternator with a hammer a couple times lol. No joke, it could possibly fix it. Maybe for a short while, but maybe for a long while. You never know with the parts store stuff these days... if it fixes the overcharging, it could possibly last longer than whatever alternator you replace it with.
