Charging issues help please.

wow something hooked up wrong or not grounded and as far as charging you smoked your regulaor now . put in a 50 or 80 we just call it a floater . But they cant take sparking or they will blow especially the stock 1ns . put a few grounds in . The old wires get cracked also and cant take a ton of voltage or you will burn it down , so check for cracks in the harness ,you may have a problem there some where and tighten your new alternator screws and bolts ,every 1 assumes they are tight from the store , just like starters you have to tighten all the bolts before you install them . good luck with it .
