I have a 67 coronet with pretty much everything new..
Guy who rebuilt my alternator, told me he upgraded it to a 55? amp. Car has an electronic voltage regulator and the gauge has been converted to an volt meter.
After driving the car for a couple of years the Volt meter acts like a amp gauge, lots of fluctiation, both up and down. Have replaced the regulator 3 times, no change..
Last night when I drove it, with my lights on, the gauge actually decharged with the blinkers making the lights dim each blink at idle. When RPM picked up all worked fine.. Now I am aware of these old stock alternators not charging much at idle, but I am pretty sure everything worked pretty darn good when this car was first back on the road.. Wonder if this is my alternator going bad?? any thoughts on here...
