Battery/Inverter Fault Issue
Hi, I have a 2010 Fleetwood Discovery 40g on a Freightliner Chassie. Last used the coach on July 31st. No issues everything worked fine. After a month in storage I went to check on it and the batteries were dead and the Red Fault Light on the Magnum MS inverter was on. The coach was plugged into a 50 amp.
The 6v batteries are 3+ years old with some corrosion on the terminals. I removed the batteries, replaced with 4 new ones, cleaned all terminals & jumpers. As soon as I connected all batteries power was restored and everything was working fine, so l plugged in the 50 amp and pushed the shore button on the Magnum display. All green lights. After roughly 2 hours, the RED Fault Light on the Magnum Display came back on. The display message said Dead Batt, Then Batt Temp. I went to the battery compartment, checked all connections. When checking, I noticed that one battery was hot, while the other 3 were all at normal temp? Read through the Fleetwood & Magmum Manuels trying to trouble shoot. Not much information in either manual.
I am thinking that one of the new batteries (the Hot one) may be bad, or I connected something incorrectly. (Should of taken a pic before disconnecting) if anyone can send or post a pic of a 2010 Discovery battery compartment showing the connections it would be helpful.
Open to any ideas or help.
Turned everything off, unplugged and turned of the inverter switch until I can figure out what is going on.
Thanks,
SCOD
