switched 12v under the hood - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I need some power for my new electric choke carb. They say dont come off the coil, hei or alternator.

Any ideas on something else to tap onto without running a new wire from inside the cab?

It would be best to run a wire to the fuse panel. Tap into an unfused switched terminal.

Yea I went back and read the OP and said switched power. Sorry, How about coming off the starter wire terminal.

I ran it out of the fuse box i was debating which one to use and now cant remeber if I used a spare slot or the cig lighter. Then I got home tonight and couldnt remember if the cig lighter is even switched. doh. I only tested with a voltmeter with the switch on. ill check that out tomorrow.
on the positive side the truck fired right up with the new carb and choke.

Cig liter is hot all the time. Well in my71 it is anyway.

yea the cig lighter is always on. went out today and the battery was completely dead. Switched it to the old radio fuse.

pffft had a couple millivolt draw with ignition off on the radio as well. Battery is getting a workout.
Changed it to another switched free spot in the fuse box and tested it at 0.00mv with ignition off.
