Ok its a 1973 CJ5 with a rebuilt 258, 3 speed. New alternator.
This just happened recently but the AMP light turned on, went off, turned on. Didn't pay much attention because the jeep had sat for a month due to horribly made new replacement parts we get to enjoy these days. Once the new rollover valve and sending unit was it though, I've been driving it daily and the light just never shuts off, even during 65-70 MPH speeds.
Checked at the battery and its putting out (At idle) 14.28 volts and with the lights on, 13.50 volts.
I thought maybe a voltage regulator but after getting the readings, it doesn't make sense for the AMP light to be on.
