Electric choke question

[thealien]

Is there any reason not to run the electric choke off the same power as HEI? My truck is a 1972 Jimmy that originally came with a points distributor and mechanical choke. I am installing a carb with electric choke and someday will add HEI. I plan on powering both off the unfused ignition on terminal on the fuse block and using an inline fuse. Is there a problem doing it this way?

Thanks

Nobody knows if it is OK to run HEI and electric choke of the same power?

I would not run anything else from the same power source as the ignition coil. You can actually rob enough power from the coil to make a difference in the coil output voltage by doing that.

You want to run a "Switched" power wire. If you run a hot, or acc wire you run a bigger chance of fire with power going to it all the time.

I would run a switched power wire from the fuse box and place a toggle switch in line with it so you can kill the power to the choke after the truck warms up.

Electric chokes require 12 volts at all times when the engine is running otherwise the choke will close.
