Wait.
The chassis was shut down for 7 weeks.
Most rigs I know will not be charging the chassis batteries while plugged into shore power. That's when you use the battery "instant switch" to get her going, then drive around to charge it up.

Or run a Trickle-Charger on the chassis battery while shut down.

Chassis battery.. Likely is dead
House battery: If MARINE/deep cycle there is slight hope it will recover
If GC-2 pairs a fair chance it will recover.

This is why I keep telling folks that DEEP CYCLE batteries (GC-2 pairs) should be kept at least half full

MARINE/deep cycle (Most Group XX) 3/4 full
Starting batteries (Chassis) 80 or more

And in all cases recharged quickly when run down.

And people argue with me.. but you just proved it.

NOW.

When plugged in measure voltage AT THE BATTERIES.. should be over 13 and a half.

But if it's not.. You have a charging issue.. Converter, Fuse (Or circuit breaker), Disconnect switch (In reverse order of suspect)

NOTE circuit breaker can be a 120 volt (likely labeled conv) or 12 volt.


Home was where I park it. but alas the.

If your batteries are below 10V the inverter/charger won’t charge them. Use a dedicated battery charger to get he up above 10V then the on board inverter/charger can take over.
