Aqua-Hot tear out and rebuild
#25

Thanks guys.

I had 3 wires i couldn't identify in the bundle of burned up crap under there and i just figured they went to the temp gauge on the master panel. That would cover at least 2 of them and i assumed the other was a ground as it was black. I woke up this morning with the thought... They wired something backwards and were using the automotive relays to reverse the polarity. i followed the directions in the install and service manual exactly and most of the blower fans don't work. I bet they it was an afterthought of how to fix it without rewiring things up above.
From the pre tear out pictures where everything is burned up i just cant make out all of what they were reversing.

Anyone willing to post a picture of how their Aqua hot is wired? At least anyone with the 2 automotive relays so i can troubleshoot this?
Those 2 relays are not in the manuals anywhere.
