Acquired a E350 Cutaway RV. It came with no batteries. looking for cabin battery hookup diagram (has about seven connections) also, has two solenoids that look like starter solenoids.
First question, will the vehicle start with out cabin battery installed (because i have no voltage driving the fuel pump circuit?
Second question, what is the second starter solenoid for?
Aide in starting of engine or used for a circuit passing or possible for generator start?
Having trouble finding correct diagrams for that year.

The wiring you are looking at is aftermarket and we do not have the wiring diagrams for you. I do know the second solenoid is used to turn on a power circuit such as the entire rear circuit. If you take some pictures and be patient I can try to walk you through it.

Cheers, Ken
