well its off to the dealer hope they can fix it

 

I have had lots of trouble with that rail sencer when I had the quadzilla rail gauge in. I went through 3 of them before i figured out the problem. On the quadzilla rail gauge on how it pigtails in to the sencer, that is a 3 prong blade plug and in the center two wires in that plug and there is NO seal wear the wires go in and water gets in there and messes with it and takes it out. that is my experience. Try to dry it out with contact cleaner and put some dielectric grease on it and try it. If that dose not work prolly need a new sencer.
