84 Bronco II Choke

[GKM007]

I have finally figured out why my choke has not been working. The grey wire that is suppose to supply power and heat up the choke heater is dead, no power.

By the looks of it feeds down into the main harness and I lose it. Is there a place I can splice that wire in and get power? How much power does it need? 12volt from the battery to much?

Yes it is 12volts

Alternator was popular spot to hook up electric choke, but has to be the older style alternator with external regulator

It is not a constant 12 volts, the computer controls the duty cycle. Are any codes present?

I dont have a computer anymore, Durasparked. I ended up tapping off the alternator lead which is working, nice to have the choke working again. Does the constant power to the heater element hurt anything?
