rhare Posted June 17, 2009 Report Share Posted June 17, 2009 Im having some minor electric issues and was wondering if anyone else might have had the same type problem. when I hook up my onboard charger, it tells me the batteries are full when infact they are only 1/3 full. I have 2 batteries hooked up on a switch with an automatic charging isolator, last year I had no issues with the system. Ive checked the batteries, Ive switched the charging isolator, checked the connections. everything seems fine. even when I disconnect one battery, the charger still thinks the other battery is full. should I look at the onboard charger itself? Do they pooch easy? thanks any help appreciated Link to comment Share on other sites More sharing options...

Garnet Posted June 17, 2009 Report Share Posted June 17, 2009 (edited) Get a multi meter and test battery should be 12+ and if fully charged 13.25. Plug your battery charger in and test battery should be more than 13.25, if it is your charger is working. You can test your boat charging system the same way.
