You need to check the battery voltage.
The shore power and solar needs to be off 2-3 hours or you are reading charger residual charge. It might take 24 hours to recharge the battery. Full is 12.6. 12 volts is the minimum. Below that damages the battery.
Was the battery disconnect used while in storage? They will discharge in a week if you forget.
If all is ok then I would be carefully checking wire connections in the battery area and fuse panel. Loose wires will do this.
Thank you for the response. I will double-check the VM meeter.
The battery disconnect was turned on while in storage.
I am thinking it is a loose wire somewhere.
