Discovery electrical problem

Question

I have a 2010 Fleetwood Discovery Diesel Class A that is on a Spartan chassis. I live in MN and it was stored all winter with all the batteries disconnected. I reconnected the chassis batteries to pull in out of a pole barn and when I went to start it the dash lights all cam on, but then started to blink and went dark. Subsequent checks, nothing happened. It never cranked over at all. I hooked up the house batteries and tried to start it and still no dash lights. I have plenty of power to operate all internal lights. Both inverters turned on and the batteries look to be charged enough to start. I noted a fuse box in the right back compartment was clicking intermittently.

I talked with a service and they felt in was something to do with the ignition system, possibly a relay or fuse gone bad.

Any help and suggestions to try before I have to get it towed would be helpful. I can't seem to find where these would be located or how to check them.

Thanks,

Todd

Sounds like the chassis battery died!Do you have an "Aux" start button on dash? This is used to start with assist from coach batteries.

Sounds like your batteries are too far discharged.  Enough to work the lights but not enough to crank the engine.

Can you measure the chassis battery voltage, at the battery posts, while trying to start the engine? It should drop a little. If it drops way down, the battery is not charged, maybe dead. If it doesn't drop you may have some corrosion or other problem in the battery/starter wiring.

My F250 diesel did that to me on a trip to SC a couple years ago. Relays would chatter, lights worked. It was a dead battery. Replaced both and problem solved.

I had this problem, my clearance lights and tail light would not come, dash, head, turn and stop would work. check fuse and the clearance light fuse was blown, put a new fuse and it blew, so ( be careful doing this ) I put in a larger fuse and crawl under the MH and trace wiring, found that the wires to the tail light was getting hot, pull the fuse and I saw doing this that one of my clearance light was out, so I change out the light and every thing work ok. What had happen the bulb did burn out but it had shorted it self out inside, a direct short. never heard or had the dealer every heard  of this. That MHing, you never know what next.
