Electric Choke - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Nima** · 10-01-2004, 06:55 PM

I have seen this has been discussed before but I couldn't find the previous threads, sorry to bring it up again. I need to know how to install the electric choke instead of manual one. I am changing the whole carb but I don't have any clue about electrick choke connection(s). Please explain it simple since this is the first time I am doing this. The wiring on the car is old one, I don't if it is original one though.
Thanks a lot.

Run a 12v keyed wire to the red wire on the choke. Ground the black one on the choke housing.

This might be a dum question but What will happen if I don't connect the choke at all?

Be real rough to start, and keep running until it warms up... A motor likes a rich environment for starting in

The 12V supply causes the choke to open, not close. If you do not connect the electric choke it will be closed all the time. You would have to jam the choke open if you do not connect the wire.

Uhh, haha, what he said

I wasn't thinkin, it'd start nice, and not wanna run later due to being too rich...

Make sure you use a true 12v source. If you hook the choke to the coil it will not be 12v (If the coil is wired correctly).

Wait a minute, does that mean theat the instr. in my Edel. 1406 were wrong? They said hook the hot wire to the coil.

The wire running to your coil, assuming your wiring is close to stock, is a resistive wire. In other words, it's not 12 volts, but more like 9v if I recall correctly. Just grab a cheap meter to check. If you don't give it a full 12 volts, it may not open all the way which would restrict airflow.

My Edelbrock 1904 instructions say 12v. The guy at the dealer I bought it from (I think Sallee Chevrolet) said to make sure I use 12v and not the coil.

For keyed 12 v wire, do I get it from fuse box?

poff · 10-04-2004, 02:03 PM

I did mine to the fuse block. There should be a few open spots in the bulk-head connector. I just ran the wire with the coil loom to the bulk-head connector and used a two into one spade adapter on the back side of the fuse block. Should be able to get the terminals for the bulk-head connector at most auto parts stores.
