Installed the troller I bought from a friend, I put this plug on it. http://www.marinco.com/product/connectpro-plug The motor worked on the first trip. Now it does not work. I tested the batteries. 12 volts on battery 1, 11.8 on battery 2. Female end of plug reads 23.8 on tester. I tried my BIL's troller, his didnt work either. So now I know that it is not the motor. So now I say WTF. The plug is designed to be put in then turned to connect. The prongs on the plug are designed to be inserted in the receptacle only 1 way. Any ideas?
