Hi all, I installed my triple gauges this weekend. Also, my generator light is coming on. Voltage across battery is 12.4 with engine off and 12.26 with engine at idle. In the car, my gage shows around 12.2 with engine at idle, 13.1 at 2500 rpm amd nothing else on, and close to 11 volts with light, fan, radio, etc on for a full load. I have an external regulator. The #2 shows 6.3 volts from regulator to ground. Also, when I bypass (jump) the regulator with a paper clip between F and 3, it takes 25 seconds to get up to 13.8 volts. I’m thinking that by bypassing the regulator, and still having low voltage, the alternator is the problem. Thoughts? Also, if I replace the alternator,would 100 amps suffice? This car is a daily driver with 455 and the AC will be fixed some day. No big stereo systems or anything else. Thanks!
