Just the battery going... or other problems?
The electrical stuff in the '83 has been acting up recently... real weird stuff like no turn signals but hazards, no radio, no heat blower, but headlights, and I can roll down the back window, no brights accessory lamp. Nothing real consistent either. The other day it wouldn't turn over at all, got a jump and started up fine. I'm going to replace the battery this week, but I'm wondering if its just the battery or if something else is shot... is there a way to test the alternator to see if it's charging? I've heard disconnect the battery when the truck is running... Any other suggestions? Its a carbed 300.
