I called and talked to Greg this morning about my boyfriend’s alternator for his gold wing and he’s the business! He’s knows so much and very knowledgeable. He pointed me in the right direction. Thanks Greg! You Rock!!A battery and charging system test always starts with a battery test 1st. But before that can be done the connections at the battery need to be inspected. Once the battery test good, then you can test the charging system. It takes a good battery to excite an alternator.
