On my Fastrak SD I dis-engaged the blades to cross the driveway and afterwards they wont re-engage? I took the panel off and checked for any loose wires. I unplugged the switch and made sure it was plugged in good after checking for any loose connections. Matter of fact I tried checking ALL connections. Still seems to have no power on the pull switch. Also checked the 2 fuses and theyre OK. Bad Switch or what?!? Looks like a trip to the shop and only 2 years old.
