I like it LOW
not s197 related, but figured I could bounce a problem off any sympathetic ear.
Have efi swapped 331 in my 66 car. Everything's been running great until few months ago. Noticed my battery voltage was dipping down into the low 12s (or lower) at times and figured out it was whenever my electric fan turned on, also caused my alternator belt to squeal like crazy, and my rpm's to drop down to around 5-600. Unplug fan and idle bumps up and alternator output goes back up to 13.8-ish
I figured it was an alternator going bad as the 3g unit I had was pulled from a junkyard car that I got for free. Replaced alternator and car is doing the same thing. Battery voltage drops whenever fan turns on and alternator screams.
Fan is wired through a relay, relay has direct power from battery. Power wire from battery to relay is like 10 inches long and 10 gauge I think.
Other issues that might be occurring? Bad ground? Weak battery? Fan going bad?
