Thanks a lot Jebiruph! Great info!My dealer really pushes back if I try to tell them anything. If you have a battery charger, I would get the batteries charged up and see if that helps. Using the Aux battery bypass jumper to temporarily remove the Aux battery from the system is also a good trouble shooting tool.
