2005 Grand Am V-6 Electrical trouble


#1

I replaced the battery and the alternator about 2 weeks ago. The new (rebuilt delco from autozone) lasted about 4 days. They replaced it. It started out at putting out 14.5 volts, and now is down to 13.3. They tested it and said the regulator is bad. I found a parasitic battery drain of about 1.75 amps, that pulses back and forth between .09 ma and 1.75 amps about every 6 or 7 seconds. I have pulled fuses until my fuse puller is worn out… I’m out of ideas.
