I'm finally going to be properly able to test this soon. First of all, I have to correct a plumbing issue I have. The original place I spliced the tank heater into turns out to send the hot coolant into the transaxle rad, so instead of heating that I was mostly heating the air. There was an increase in the transaxle temp as read by the scanner, so it was working, but not very efficiently. I will now set that up properly so most of the 750 watts will get where it's supposed to go.
