Hey guys I need a little advice trying to figure out why my battery wont charge. The battery can be charged by a tender and will hold the charge, but the alternator doesnt seem like can charge the battery. The weird thing is the voltage reads fine when running. I get 13.4 when at idle and 13.5 when revved. Any thoughts?
