A friend of mine has a 1990 dodge caravan that will not charge the battery. The alternator, the battery have both been tested. The wiring from the positive to the alternator and the negative to the block have both been checked.
Use a volt meter and check the voltage with the engine off. should be 12 volts then check again with engine running it should be 13 to 15 volts if no then the pcm is at fault. the voltage regulator is inside the computer control and you will need to have it checked out at a dealership. if bad will have to replace the computer on van to correct the charging system. hope this will help!!!
