I just picked up a 2012 pro, the gauge does not power up and the tail light does not come on. headlight works and the handwarmers work. I unplugged the harness that goes to the tail light did not change anything. I bought the chassis w/o a engine and put a engine in. just wondering if this has happened to anyone else and what to look at I have gone over the sled and can't find anything but I'm sure its something I missed
