Battery Issue

Having a battery issue and hoping someone can help. While changing the house batteries I tried to tape all wires together for each battery post. When pulling the second battery out all the tape fell off and mixed up the wires. I called Thor and they sent me a schematic for my coach and I installed the wires according to the schematic. However, the wire for the emergency solenoid was connected to a 50 AMP circuit and not the house batteries, but the schematic Thor gave me had both attached independent of each other.

The newly installed batteries were showing a low voltage (11V) on the digital display on the inverter. So I started the rig up in hopes of charging the house batteries. The engine ran for about 30 seconds, the RPM increased and then the engine died. I restarted the engine and the same thing happened. When I tried a third time the rig was completely dead and nothing worked. I replaced the Chassis battery and still nothing. It is as though there is no chassis battery installed. I checked the 100AMP chassis battery breaker and it not tripped.

I also tried the emergency start and it is not working. As I write this according to my volt meter all 3 batteries are fully charged. Any ideas of what I am doing wrong? The house batteries are working for the electric inside the coach, but I cant get any power to the engine.
