how dose the elecrtic choke work and can i hook it to a switched power source so i can cut the power to it when the car isnt running?
There is a wire under the dash that is not used that comes on with the ign. switch that is perfect for the electric choke. Don't connect it to the Stator terminal of the alternator (its not 12 v), the coil wire or the IGN terminal of the starter relay because they take power through the ignition resistor which is not 12v and takes power from the coil. If all else fails you can tap off the fuse block at a switched power point. Be sure to get a wire from the ignition side and not the accesory side.
Wow! Not trying to argue, but mine was connected like that from the factory! The 6 and 8 cyl might be different, though. Mine's an 74 Maverick 250 auto trans.
The Ford electric choke is designed for the lower voltage at the stator terminal but Holley and Edelbrock need 12 volts. Mine had the choke connected to the stator terminal too - it was a Ford Autolite 2 Bbl carb and not an Edelbrock.
The electric choke on the SS 650 Quick fuel carb comes off too fast. Its completely open in 20 or 30 seconds. Choke heater has 14.5 ohms resistance. Picked up this resistor Aluminum-Shell-Resistor-Power/dp/B005DPP36I/ref=sr_1_1?s=electronics&ie=UTF8&qid=1324393064&sr=1-1 to put in series and slow it down. Haven't installed it yet to see how it works.
There should be instructions with the carb on where it connects and how to adjust it. I suggest you read them first.
Yes, you're rght. Did read them and it said 12V so its not designed for the stator connection. But it comes off too fast with 12V. Hope the resistor will slow it down.
In my experience w/ my Holley 600 is it needs 12v to work properly. I had an instance where the "12v" connection was dirupted and the outcome was the car wud not idle after it warmed up. I cud barely keep it at a stoplight it was idling so fast. I made an emergency repair directly to the battery until I got home and put it on a known 12v source and have not had a problem since. So, I agree w/ Paul S - Holley's need 12volts.
