Most likely your switch has decided to retire, if you had a loose wire it probably would have quit when you didn't want it to, hope that helps. | | | | | Joined: Apr 2008 Posts: 643 'Bolter | | 'Bolter Joined: Apr 2008 Posts: 643 | THANKS,kinda was thinking the switch finally gave out.Ordered one just in case-

A friend of mine had this problem, seems the alternator provides the power to keep it running. He had to install a diode to keep the alternator from feeding back to the ignition system. | | |
