I have a 77 Royale with a 455 and 6kw onan. The onan has its own battery with a 2 gauge + running from the Generator up to the engine compartment. There is a house battery and coach battery in the right front of the engine bay. In the fire much of the wiring on the firewall burned away but most of it has been identified and replaced but there are a couple of small remaining mysteries. On the heater box which houses the evaporator and heater core there is a device which has four wire taps or blades for connecting wires to it and some coils or resister type things protruding off the other side. This part mounts in a hole in the drivers side of the heater box and protrudes into the box. What is this thing and where do the wires from it go??
On the passenger side of the heater box but mounted high on the raised firewall electrical panel is another device which looks similar to the horn relay. It is badly melted and has nubs of wires coming from it. Anyone have an idea of its function and how it is to be wired?
Hopefully my description is not too vague. Any links to photos or instructions would be greatly appreciated.
Thanks,
Sully
