This is the second time since I bought my truck In February that I left the ignition switch in the on position. The first time I burned up the coil and this past Friday while troubleshooting the gas gauge I killed the battery and burned up the points. They now are pitted and need replacement in addition to the battery being dead. Who know what else I may find!

Is there any way of protecting the ignition system from burning up, if I leave the ignition on again. Maybe a relay or diode or something?

Good question. I and am sure many others have done the same thing. I guess one could install a relay to get around this self induced error, better known as ‘operator error’. Interested in reading how others might have solved this issue.

Definitely ‘operator error’, but as my mind is aging I can see this happening again.

Someone back a while ago said to hook up a bell or something to let you know the key was still on.. not sure how that worked out. Especially since half of us are hard of hearing in one ear, and can't hear out of the other, not to mention tinitus.


Another quality post.

If you have an alternator, you can hook up the idiot light to show if the ignition is on, but engine not running.

Or you can install an oil pressure warning sensor/switch for a light.

A simple solution could be to use a single filament 6 or 12 volt bulb, depending on your battery voltage. Solder a couple of leads with alligator clips to it. Hook one lead to coil primary, other to ground. If bulb is lit, key is on. I think that would work even with points closed but not sure as I’ve never tried it.

the coil primary has a good chance of stoping with the points open so your bulb wouldn't necessarily be ON with ignition on.

however if you want a small light /or buzzer to be ON only when ignition is ON and engine is OFF you could connect the bulb or buzzer between ignition power and the GEN. / Armature post of the generator.
when the ignition is ON and engine OFF, the buzzer / light will sound because the generator is such a low impedance compared to the buzzer / light to ground that it would have basically full battery voltage.
when the generator is producing power, the shunt relay closes and your buzzer / light would have 0 volts across it.

One could put their house key with the ignition key, of course, if you never lock your house, that wouldn't work either.

The problem arises when I am working on the truck in my garage. If I was driving it, I would need to turn the ignition off to stop the engine.

I do like the idea of an idiot light. I have a 12v system and a one wire alternator. How would I go about hooking one up?

Does your one-wire alternator have a connector on it with a short jumper to the BAT terminal?
