quote 65sunbeam:

I don’t think it draws much current (anyone know?) so I would connect it to the side of the fusebox that is hot when the ignition is on. You only want voltage going to the choke when running the car anyway. If it does draw a lot of current a separate fused line could be run from the connection on the voltage regulator that is hot when the ignition is on. Say several chants to Sir Joseph Lucas when making these connections and everything will be fine……………Eric

Yes they do draw a lot of current, and it is on all the time. If you must use it, run a new fused wire from the main regulator terminal to avoid system volt drops which affects lights, ignition etc.

I modded my current Holley, and I am modifying my Carter to manual choke before fitting it as the choke is only needed for about a minute max after getting the car started.
