I have been forgetting to turn my headlights off alot lately on my 66 american and tonight it resulted in me having a dead battery. How can I wire a warning buzzer (like my eagle has) to alert me when my lights are on? I used to think those warning buzzers were stupid but now I think they are great and want one on my american. Thanks.
I've done the same thing; I like my cars primitive but there are times...!
It's electrically easy -- a buzzer in series with a diode. You wire it between the headlight switch (lamp side, not battery side) and the IGNITION terminal.
The diode is wired so that when the headlights are on, it tries to power the car; it won't, and can't, because not enough current will flow through the buzzer, but it iwll make noise.
If you're not comfortable making one, I'm fairly sure AMC used a headlight or key buzzer that is a plain buzzer with a diode built-in. Just gotta find which one!
