I just bought a used 600 cfm Edelbrock electronic choke carb. The carb is in great shape. When I hook up the choke electrical wires, the choke will not operate. The hot wire is getting a full 12 volts when it is not hooked up to the choke ( when ignition is "on" ). But when I hook up the + lead the voltage drops to 1.5 volts and the choke will not activate when it is cold or hot. What do you guys think. Let me know if you need more info too.

Have you hooked a ground wire?

Probably a bad connection at the source of 12 volts.

When there is no load, wire disconnected, 12 volts will be there, no current draw. Connect the wire, heavy load, not enough current to handle the load, lower voltage.

May also be a bad choke cap. However, a quick check would be to hook cap independently to the battery and see (feel) if it gets hot and opens the choke, If it does, then you know it is the source of 12 volts.

I'm sure you're not using the ignition wire, hopefully, your using a switched 12 volts from the ign switch or fusebox.

Thanks Everett, you were right on. The connection I had was not handling the load. Switched it last night to another terminal in the fuse box and it works perfectly now. Thanks again.
