Greg,
I decided not to hook into the glow plugs and plan to give the fan its own switch. There’s a spare switch next to the auto-start on the control panel. Jon suggested adding a switch with a timer.
I’m not clear on what you mean by using the preheat lead to close the circuit. I didn’t think I needed a relay. I’m unsure how many amps the fan pulls, but I don’t think a simple toggle switch would have any trouble handling it.
I’d prefer to keep things as simple as possible. What do you think?
Thanks, Rodge. I went out there last night with a drink and just stood there, taking it all in. I’m sure you’ve had those moments too.
