Thread: electric choke conversion

Tweet

Just trying to convert my q-jet 4 barrel to an electric choke. I bought an electric choke from BFIC in CA, what they sent was just that, 1 piece, an electric choke. Does anyone know what voltage to hook it up to? My mustang uses 6 volts, and where might be the best place to run a wire from ( and gauge). My engine is a 283 with quadrajet 4 barrel in a 1957 willys CJ5.
Thanks...Paul

Mustangs all had 12 volt systems and so did any thing that used a quadrajet, That lectric choke will only work on with 12 volts going to it, and will need to only have power to it with the engine running, it could be used with an oil preasure switch, or the most common is from the back of the alternator (G.M. style)

if I hooked it up to the back of the alternator, where would it connect to? Also, I read about maybe hooking it up to the acc connection on the ignition switch. Thoughts on that??

First tell me is it 6 volt or 12 volt system and does it have the standard 3 wire G.M. alternator ?????

12 volt system, with an older 3 wire alternator. The jeep used to be a 6 volt system, but it was converted to 12. Also, much of the wiring is old and cracking, eventually I am going to upgrade the wiring to new and the alternator to a newer internal voltage regulator type. So what about the acc connector? or maybe connecting it to a bus bar?

I would hook it up to the fuse block. Use a volt meter and find a fuse that is for acc. (the power only goes on when the key is turned to the acc position.)

Sorry I didn't get back to ya till now, use a 12 volt test light or volt meter and find the wire on the back of the alternator or ya could go to the voltage regulator and find the wire that is hot only with the engine running, hook your choke wire into that, be sure and not use a gasket on your new choke thermostat as it will need to make a ground on the choke housing, also you will need to look in the choke housing for a small hole, This was the vacume circuit for the old style choke, You need to plug this hole, a little J.B.Weld will work just fine. put your new elec .choke stat on, turn it counter clockwise will holding the throttle slightly open, turn it till it just closes the choke butterfly and lock it down, now hook a piece of vacume hose to the choke pull off and suck on it, it should crack the butterfly open about a 1/32 to 1/16 of an inch, you may have to bend the choke pulloff linkage to make any needed adjustment......adjust your fast idle screw so she idles about 1200 rpm and you should be set, choke should go full open in about 2 to 3 minutes with engine running.......

sounds good to me..easy as pie I hope. I will give it a try and let you know what happens..thanks..

I was wondering how the electric choke conversion kit actually performs. I contacted the same people to get a kit for my Rochester Quadrajet and I would like to have a little information on how well it performs before I buy it and convert. Thanks

They work just fine, G.M.used em from the early 70's untill the last carb engine in the later 80's......
