After replacing alternator bracket and power steering pump, I took car around the block for a spin. Car was idling a bit high at first. Drove it 1/2 mile then fell on its face. I knew the problem, the up pipe sleeve slipped off of doghouse because of a clamp slipping off. Fixed it drove home 1/4 mile anf parked it. Fee days later took around the block and suddenly died. Wouldnt jump start. Hooked up chain towed home. Still dead. Dash not lighting up, I hear the dinging at tone turning key but dead, everything on dash. Headlights come on but low. Voltage getting to the starter after putting probe on it, lit up. I believe battery not quite putting out a full 12 volts but even eith charget hooked up and jumping it when first died, nothing works. My lap top with direct scan will not interface.
