alright guys,just swapped in the cam'd up 306 in my 77. im using a junkyard explorer serpentine system(reusing the alt that cam with it)
everything has been doing good so far, started driving monday...no problems til today. got off work, headed to pick my daughter up from school(no problems yet)
got back in, cracked it up and started driving...couple blocks down road and noticed engine light was on. started looking around for clues and noticed the volt gauge reading below 12. when i put a blinker on the pull off road...looked like it was flickering and dropping close to 10v. so i shut it off, popped the hood to see if i lost the belt, a wire or anything....(NOTHING)
cranked it back up and no engine light, volts reading 14...so i went to O'Rileys to have the alt checked. he told it was good, charging @14.1, diodes were good and was putting 64 amps out...
im kinda stumped...can the volt reg maybe drop in and out?? maybe slowly going bad? I thought the 4G alt was 130 amps? maybe not at idle... just dont want this alt to bite me in the A when i least expect it
