The Old Man and No Barth
| Hot switch suggests high resistance in the circuit, maybe in the switch, maybe in the connections, maybe elsewhere. Bad connections are most likely. Try pulling the switch, cleaning up the connections (they're probably standard automotive spade connectors). If you want to be sure, go ahead and buy a new switch, unless, of course it's something exotic and expensive that you can't get at your local auto parts emporium.
The intermittent on-off situation could be a loose connection, a bad wire, or there might be a breaker in the system that cuts out when there's too much resistance, and resets automatically. If it's the latter, and the do-it-yourself steps don't solve the problem, it needs a hands-on diagnosis by a pro.
If you pull the switch, check all the wires for corrosion, and possible broken strands where they're attached to the female connector. Odds are, the original connectors are crimped onto the wires, and these connections, though good, quick, and easy, can corrode over time, and develop high resistance. Also, vibration can cause strands to break. If too many do, that's trouble, too.
Make sure all your wires are solid, and everything's clean, neat, and free of corrosion, and the odds are, your problem will be solved.
Anyone with other ideas is welcome to chime in. At 75, I've seen a lot, but I don't quite know it all yet. |
