2007 YDRE 48V with XCT500 amp controller and Plowman motor. A couple of months ago I installed the new controller and motor at the same time, and right away I noticed the motor would get hot as hell, which Don said it would do until the motor "breaks in". So I put about 60 miles on it driving under different conditions and never holding it at WOT. Even after that initial 60 miles, the motor would still get very hot, like couldn't hold your finger on it for more than a full 1 Mississippi, and I was getting hot electrical smell. Recently I started hearing this weird hissing noise but only heard the noise when you first pressed the throttle, and the noise was intermittent. I also noticed that my fan on my controller would come on right away, sometimes before I even backed out of the garage and onto the street. When other times, I could be out driving around for an hour and never hear the fan come on. I'm not 100% sure but I feel like every time the fan would come on so soon, I'd get the weird hiss noise...... So last night I was looking things over to see if I could see anything, and found this, J9 motor positive wire burned up. I've got a call into Don, but have not heard back from him yet, and thought it'd be a good idea to get additional info on this. I've also got an email into alltrax to see their thoughts. Thanks for any input.
