Review on 🔌 Atwood 91365 Circuit Board Kit: Optimal Water Heater Performance with Gas/Electric 12 VDC Compatibility! by John Bones

I've tried half a dozen of these boards. I asked Atwood for technical assistance, but they didn't do it. They sent me a replacement board but they will not hook me up to electrical circuitry or technical support. I feel like I fried these boards because of the high voltage, but they won't respond with instructions. High voltage from my tractor when charging the battery (14.4V) when connected to a trailer and the water heater is on. Also, my trailer went down from 24v to 12v, it worked fine at 12v but when switched to a higher output voltage (13.6v) the hot water heater board was switched. I needed a higher V to drive the jack motors. Your answer is to contact the official dealer. But they won't work on it due to my modifications. So Atwood doesn't help.
