tested the alternator with both a meter and,alternator tester. It says all is well. the battery light still comes and goes. I rewired and cleaned up terminals and it was good for a while. is there a relay of some sort that could be sticking. what could be some other causes of intermittent alt problems. the alternator is less then a year old and hoping not to change that thing again. who came up with that design. thanks richie..
