1993 Plymouth Acclaim 4 cyl Front Wheel Drive Automatic 143368 miles
Initially I got a " Check Engine" light (lower right instrument panel), then the battery voltage meter dropped from 14V (normal indication since I purchased the vehicle in 2007) to 12V -- meter reads 8 at the lowest mark, and 18 at the highest mark with four tic marks in between, and finally I get a " Check Gauges" light (middle of the instrument panel). After the car sat for an hour or more, all the indications were clear. After about ten to fifteen minutes of running, all three indications came back. This occurred three times today. Then on the way home (about a three hour drive), the car died. I found a shop that charged the battery, and I was able to drive the car home.
How do I tell whether it is the alternator or the regulator (I was told the regulator is on the PCU board located outboard of the battery)?
