[QUOTE="Boat2fast, post: 344386, member: 13358"] Quick test to see if the charging system is working: Put a volt meter on the battery. Note the reading. Start the engine and rev it up a bit. If the volt meter rises with the rpm above the battery voltage observed before starting, then the charging system is working. In order to charge the battery, the charging system has to put out a higher voltage than the battery. Just look for the increase. You'll know in a few seconds after starting the motor. It's not unusual to see 13.5-15vdc. [/QUOTE]
