After charging batteries ( two coach and one engine ) reinstalled and tested and all was good. This was Friday and on Sunday went out to move slide out and it would not. Turned on the ignition switch, dash lit up for about 10 seconds then heard a clunk noise L/F, maybe under dash and everything quit. I have no power through out the coach. Any idea what might have happened. Weather here has turned really bad so have not been able to do any check at all, thank you in advance for your help.
I have a 2003 Itaska W/H chassis batteries sit under step easy to access. Odometer reads 74,000 miles it has been well maintained I purchased it two years ago.
