I need some guidance in figuring out what's going on with the voltage in my '77. Started it last week and everything was fine. While idling I pumped up the air bags. My digi-panel alerted me to the fact that voltage had dropped below 11 (went red), but the gen light on the dash didn't come on. Next day, everything was fine again, but after about 10 minutes of driving, same readout on the digi-panel. After that, only red on the digi-panel, still no gen light. Replaced alternator (6 year old Duralast from Autozone) and charged battery (it was a bit low). Now, voltage is steady but still low: 12.89 at battery when not running, 12.77 at battery when running. Battery tests OK. I cleaned grounds and tightened connections. What's next? Another alternator or ?? I do have the standard battery disconnect switch on the firewall and boost switch on dash. Thanks!
