Thank you for the input. I am going out to the storage location tomorrow to check it out. I will see if the house batteries are dead. I just replaced the house batteries so I think they will be ok. I also know the motorhome has the aux start function so hopefully I can get it started using that.
The kill switch is located in the of the motorhome. The only thing I know is you can kill the engine from the back "trunk" area. The switch also prevents you from restarting the engines. Not sure if it disconnects battery power or what.
Some days I really miss diesel dave.. thanks for the help!
