48volts on all motor terminals

[pbearros]

I have been going over this 2004 precident all week. It had no batteries at all, I purchased a new set today and installed them. I discovered a couple of connections to the motor that were not according to the diagram and corrected them. I was able to get the wheels to turn briefly but only in reverse. That was regardless of the switch position, forward or reverse. One position gave a faster rotation but still in reverse.
I have double checked the wiring and disconnected the motor to check it per the manual. It checks good. The last time I tried it I heard a hum but had no rotation. In checking the motor terminals I found 48 volts on all 4 terminals.
Having the key on or off made no difference so I disconnected the batteries for the night as I had other things to do. Sorry, I have done no searches and don’t know where to start on this tomorrow. Any advice is appreciated.
