OK. It has been quite a while since I first report this issue and the dealer has done nothing. Since it was intermittent, they could not duplicate it. When I had in in the fall, I don't think they tried. Last week I brought it armed with a video. Of course it was like pulling teeth to get anyone to watch.
Finally, the called and said that there were no problems and the only time they could duplicate the issue was when it was plugged in and attributed the 6.5 am draw to the trailer being plugged in and the inverter was draining power. ????? They basically laughed at me and said that there was nothing they could do except sell me a pair of 6v batteries.
Last weekend, the same thing happened and zapped the battery. This time, I had a hard time getting it to stop drawing 6v, maybe due to the low battery charge at the time.
Anyway, Yesterday I sent an message to the Wildcat Maxx Facebook page and customer service at Sureflo stating what I had been told on this thread. Sureflo wrote back and recommended adjusting the pressure back 1/4 turn and sent a diagram on what to do. The pump already sounds different when turning off. We'll see what happens when I take it out.
So much for warranty service at the dealer.
