Two Electrical Questions
Folks, I am rewiring my 56 F100 and have two questions:
I would like to illuminate an LED on the dash when the ignition is ON, but the engine is not running. I am thinking to use some type of voltage sensing switch, or maybe RPM sensing, as both paramters will change when the engine is running. But I've not come up with anything.
For the rear, my brake lights do double duty as turn signals. So if you have the turn signal activated while pressing the brake, like at a stop, then essentially I need to flash the brake light on and off. The only way I have figured out to make this work is with cascaded SPDT relays. It should work, but seems cumbersome. I wonder if there is a cleaner way to do it.
If anyone has input on either subject I am all ears. Thanks.
Gustave
