Fuse panel question
Is the ACC terminal on the fuse block a "key-on" terminal and is it a good place to run a direct lead from my electric choke to this. The place where I had my Q-jet rebuilt and converted to an electric choke said that running a 16 gauge wire directly to the fuse panel instead of tapping into the power lead on the windshield wiper motor is the preferred way to go. Has anyone else done it this way? Where has everyone else gotten the power from to operate the choke?

It's from the Ignition switch,, is key on only, and is fused at 10A along with the Radio and the air door in the hood and some other under hood pieces. Perfect place to draw power from for this app. Crimp a lug and plug it in. I made a 3 wire short pig tail with a yellow female lug with 3 16 gauge 2" wires crimped into it,, so I can hook up 3 diff things to the fuse box Acc lug.

I'm not sure I'm following you correctly, so your saying that the ACC lug will work as a key-on place to plug into? The one marked IGN already has something plugged into for the power windows.

According to the schematics that I have,, the ACC output is hot when the key is in run and acc position. It is not hot when the car is being cranked,, which you would want, if it's going to be powering the choke, as you want to cut down on the air to start it cold. I would hook it up to the Ign lug, it's hot in run and start but not in Acc,, you don't want to drain the batt powering the choke while listening to your radio. You want to use the Ign lug on the fuse box. You will need to build a pig tail with 2, 2" 14 gauge wires crimped into a SINGLE yellow female lug, and then 2 male blue male lugs crimped onto those. One to the existing power need,, one to the new choke lead. Insulte the ends of the wire as needed, if not plastic shielded. I included a pic of how to crimp if your not familiar with it.

but now I'm interested,, what controlls the on/off to your electric choke? Something has to controll it's on/off function,, I would think it would be a temp sender somewhere, but I don't know. You need to find out what controlls the on/off functon of the choke. I can get you the power correctly, but I can't say if it should be hooked up or not. ask here or your carb rebuilder,, but if they advised you to use the ACC lug,, I might not trust thier advice.

They said wire directly to the fuse panel, I was the one who asked if the ACC lug would work, they didn't suggest it. I just asked because it's an open lug. I don't understand how it works either, all I know is that it's a one wire hook up. I don't know what makes it open up as the engine get warmer, I'll just have to try it and see. If it doesn't work I'll call them and have them look at it. I know it grounds itself through the carburetor somehow. Maybe someone else will jump in and explain exactly how it functions.

I have mine hooked to the ACC terminal and it works fine. The downside is that the choke will warm up if leave the key in ACC and make the car hard to start when cold. I have no reason to leave the key in ACC and listen to the radio so it is not a problem.

Electric chokes are not controlled by temp senders. They are self contained devices. They are closed when cold. As electricity is applied to the bimetallic spring coil, it warms up and the choke opens. An electric choke has power applied the whole time the car is running so it stays hot.

use a wire from the acc lug to control a relay. the relay will close a circuit from the horn relay red wire (thru a circuit breaker). that way other items can be contolled without danger of poping the 10 amp fuse and also eases load on ignition switch.
