I own a 2008 Thor Mandalay, 425 ISL Cummins with a Magnum ME 2012 inverter/charger.
Never had a problem starting the motor until this AM. I pull it out of storage about every two weeks and run. This morning I went to start the motor it would turn over but not enough to fire off, indicator showed low battery.
I put a strong charge on the battery to about 13.5 tried to start could not get a contact, it was like the batteries were disconnected, all cables were tight, no corrosion on post, I checked relays and fuses related to starting. It is like there is a lock out somewhere.
The last time I pull the coach out one BR slide would only come in half way and stop and start the wall locking mechanism (like it was fully retracted) I finally was able to retract the slide to full and locked in place.
I am not sure if this slide has not cleared safety switch and keeping the motor from engaging.
I do not have drawings on the slide switches to see if I could override and have no idea where to look.
