I'm dreading digging into my Webasto. P.O. unhooked a lot of things and I'm uncertain the last time it was used. Might warrant a "rebuild"
Can't be any worse than when I fired up the Webasto on our old 4106 for the first time. Started smelling roasting chestnuts, and then looked out the window to see a stream of flaming red-hot acorns and walnuts flying from the end of the exhaust pipe. Couldn't shut the thing down fast enough.
WOW! is that a Craftsman screwdriver? Neat. lol
That coil looks very different than mine. Mine is round and looks like a gas engine coil. Or like a Harley coil with two outputs.
