My Ultrex is working great ( knock on wood) but when off the on button light shows on about half the time. I know about the open circuit to turn on. I have read on here about tightening the two connectors to switch to prevent the open circuit and light on. I would like to try that. Would someone give me a little detail on how you tighten the connectors up a bit? After I tighten should I put some dielectric grease on them as well? Going to do this Monday so help appreciated!
