I am sure you are correct, but since I just stripped the head of one of the screws and will have to wait until tomorrow to drill it out, I won't be able to check the switch tonight. Since I have you on line and we are already this far... if the switch and wiring prove to be OK, what other component if any, might cause the condition and should be checked next?
