'83 Ranger Electric Choke

Hey All,
I've recently gotten an 83 ranger 2.0L from a farm. The engine's been swapped out and they did a real butcher's job with the wiring. The carb choke is held open with a bungee cord!! I've applied 12 volts to the choke and it does open after a little while.
If it was hooked up properly, would a constant 12volts be going to this while the engine is running or does some relay cut it off after the engine warms up?
Looking at the wiring diagram that the book says i should have, it shows the electric choke wire going to the back of the alternator and then that wire continues to the ignition control module. Unfortunately i don't seem to have the same connections on my ignition module for this wire. Can i just rig a wire tied to my ignition so that 12 volts is always on the choke or is there a better way?

OK, here's what i've found so far. I've seen more wiring diagrams which show the stator connector from the alternator as the contact for driving the choke. I've even found the wire with the connector at the right distance to make the connection. The problem: NO Voltage at the stator connector on the alternator. Seems kind of odd because my battery isn't dying, so i assume my alternator works. Oh weel, i found another 12 v wire that was dangling and was only powered while the key was in the run postion. i hooked that up and i seem to have electric choke working properly now.

The electric choke does indeed get its power from the stator wire off the alternator on those engines. Were you checking the voltage while the engine was running or not? There will be zero volts at the stator when the engine is off because the stator voltage is controlled by the voltage regulator.

The electric choke cuts itself off with two bi-metal strips inside the cap. One is sensitive to the heat generated by the electrical current flowing through it, and the other to ambient temperature. When either one opens, it opens the circuit and shuts off the electric choke. By the time either opens the engine should be warmed up enough not to need it any longer.
