generator weirdness

[dhardy1944]

Thanks Don,

Now that you mention it, I believe I have heard the relay from the
driver's seat when engaging the aux switch. And yes, the voltage
comes up immediately on the gen battery when I do that. I hope to
check that and a couple more items in the morning or afternoon.
