I picked up my 78 Royale rear twin from Bryan Wheat last Friday. Finally getting around to some issues before heading out on a 2000+ mile journey in early April.

Currently they are;

Oil Pressure gauge is pegged to "H", doesn't back off after a reasonable time

Low Engine Coolant light on constantly

Remote start for 6000KW Onan not working

Below is what I have done so far. Let me know if I'm doing anything wrong or if here's something else I can do.

Oil pressure switch - I removed the wire, gauge remained on "H". Grounded wire, gauge went to "L". I suspect bad sender. Is this a component that I can get locally? Or do I have to order from Applied or Coop?

Low Engine Coolant - PO stated that it possibly had a bad radiator probe. Waterpump had been recently changed. First I check the coolant level. Overflow was empty. Filled radiator and overflow tank with coolant. While checking the location of the probe I discovered yellow wire to probe disconnected. Reconnected wire. Started up engine and let it run for around 5 minutes. Low Engine Coolant light remained on. Reviewed troubleshooting procedure in shop manual and it instructs you to disconnect probe wire and the Low Engine Coolant light should go out (it didn't). It then directs you to replace the Low Coolant Switching module. Should I go ahead and replace or wait a couple of uses before replacement

Remote Generator Start - Generator will neither start or stop from the remote panel by the galley. I haven't opened up the panel yet but I suspect it's just the switch. I'll try bypassing the remote switch with jumper (Switch Pin 1 to 3 for start, Switch Pin 1 to 2 for stop). Any other ideas would be helpful.
