Electric Choke Wire

I'm installing a new Holley Avenger carb with electric choke. I know not to put the hot lead from the coil side of the resistor, but is it ok to use the side that comes from the ignition switch, or, is there a better place to connect it.

It has been covered before, but I do not mind going over it again. The proper way to hook up an electric choke is through a relay. One side of the relay coil is powered by the field coil of your alternator. The other side of the relay coil goes to ground. 12 volts from a fused source goes to one side of the normally open contacts of the same relay. The other side of the normally open relay contacts goes to your electric choke. With this configuration the only time the choke gets power is when the engine is running. When you are messing around with something else and you have the key on the choke is receiving no voltage.

Doc here,

General Mystery (GM) , usually runs a Choke RELAY off the Field wire of the alternator..(the brown wire).

In this configuration , the choke will not begin to open until the engine is actually running..so you don't attempt to start a cold engine on a wide open choke because you turned the key on to wash the windows , listen to the "Tunes" while loading the car, or Belting the kiddies in..defeating the purpose of the choke.

The Alternator MUST be putting out power (Engine turning) in order for the Choke element to get power through the relay from the battery before it opens AND must be "bumped" to slip the mechanical detents to return it to curb Idle.

The whole process takes about 3 minutes..and saves a lot of jump starts in a cold climate on a badly tuned car, with an older battery.

Doc here,


Well then...

You can do it the OTHER way General Mystery Does it...

Obtain a Combination oil pressure / Switch sender...Where i/2 the switch is a pressure sender, and the other half is a standard on/off pressure micro switch..(tuns on around 10 lbs..)

The last option, is of course, any Fused (25 amps) Switched , 12 volt source, THAT is not the coil or alternator..But this gives you the least amount of control/failsafe over the choke.
