Actually David, since your are the electrical wizard I'll ask you if you
know how to set this up:
What I would like to have is two LEDs on the dash instrument panel... one
that would light if the fridge is on 12v and one the would light up if the
fridge is on propane (that's the hard one). And both LEDs would be off if
the fridge were off.
Now how would I do that? Where would I get enough power to light the propane
LED on the dash when we barely have enough power to light the stock fridge
LED on the LED panel?
Thanks,
Bill
