Default '84 choke

I did google searches and everything, I'm ordering a new one on eBay tonight, but I don't understand how it works. When should the yellow wire have power going to it? When the key is turned or the engine is running it's getting .84(ish) volts and makes a light clicking noise when the key is "on" but the engine is off. So is the metal spring supposed to open it when something gets warm, or is there a small electric motor/servo that's supposed to open the choke? When I bought the truck the guy had a vice grip down the throat of the carb holding it open and I'm pretty sure that's not how it's supposed to be.

Joice going to the choke comes from the alternator, so the engine should be running to make it work, do you have the right wire hooked up?

I'm pretty sure it's hooked up right, but even when directly hooked to the battery it didn't do anything at all so I'm gonna pick up a new one.

Inside the cover there is a thermostatic(heat sensitive) coil spring, the electric heater warms the spring, it in turn expands to pull the choke open. Before replacing the choke assembly, get a manual with the specs to set the choke and the proper tools/gauges if required to set it up. In the past, I used to change the thermostatic choke for a cable operated manual one whenever I had issues with thermostatic one acting up. Another thing make sure the carb and it's linkages are clean, otherwise they won't work properly.

I ended up popping the rivets out and taking it apart as I thought it was broke anyway. The 2-3 discs (I'm assuming they're used as resistors) were broke on the inside (Wasn't from me popping rivets). I'm just going to order a new one as the linkage and everything looks and feels new, it all moves freely.
