Looking for hopefully an easy answer on where to connect the power wire for an electric choke, instructions say not to use alternator or coil but to run it to a keyed accessory. The wire it came with isn’t very long, is there a good point to connect to inside the engine compartment. I’m pretty clueless when it comes to electrical so as basic as you can make it would be appreciated.
I have mine connected to the stator terminal on the alternator. Work great
Below the ignition switch under the dash is a three receptical female connector with a yellow wire leading to it. That is the acccesory jack that is keyed on / off. Fabricate a lead with a fuse /2amp/ that plugs in there on one end and connects to the electric choke on the other end.
Ok awesome, any more detail you can offer on how to fabricate that lead? Sorry like I said, I’m pretty significantly electrically challenged.
I installed a relay under the hood triggered off the + side of the coil. Did it this way to power the electric choke and supply 12+ volts to my Pertronix unit.
Royce has a simpler method for you though.
Sure is easy to use the stator connection on the back of the alternator. Ford did it this way when they started adding electric chokes. No output until the engine is running and the alternator charging. This assumes you have the stock type alternator.
I also use the stator connection, but, I’m not as careful or knowledgeable as Royce. No bad consequences, though.
I think the carburetor company is afraid that home made wiring to the stator connector might inadvertently become grounded which might take out the charging system. Using wording like they have it covers their butt legally. It also makes you do it like they said if you want the warranty to be in effect.
What ever you do be sure it is made well enough to survive long after you are gone.
STA terminal, with a fuse in line.
Thanks for all the replies, I may just go with the alternator if I can figure out where the stator terminal is lol
Or did I just get lucky? I see a red wire in this photo, cut, folded back on itself and taped, assuming if it has 12v when the ignition is on and not when it isn’t it should be a good power source?
STA terminal is on the back of the alternator and is marked “STA”.
That is true but only for the 1968. Some 69 on up have an accessory fuse extension (I call it the fuse buss extender) on the diagonal slotted area in the center of the fuse box that you can use. All of these are ACC power, so your electric choke will be powered on if you put the key to ACC prior to starting the car for an extended period of time.
Good catch! I should have noticed he had a later Cougar.
I don’t think you would want to put power on the electric choke by turning the key to ACC for any period of time prior to starting. Power opens the choke. Lack of power is what lets it cool and close for cold starts.
I know holy thread resurrection!
I’m looking to go the relay route for the electric choke and a future Pertronix conversion.
The question I have is where did you source the +12V from and what Relay/rating did you use/recommend?
You would not use a relay for the automatic electric choke. Just connect the choke wire directly to the STA terminal on the alternator.
