Put the battery back in and check for power at that wire with the key off...and then with the key on.

Off 0 volts, ignition 10.5.

That's a winner!

Battery is only showing 11 ish.

                       No, not from coil   :nono:
Uh Oh! why not power from the coil?  I have been doing it like that for 20 years.  what issues am I causing myself?

it looks like once the car is running the voltage drops potentially causing your choke to not operate right. I don't think it's really hurting anything though.

The extra load of the choke would increase current in the coil circuit. That increased current would and the addition of the choke, would change the voltage drop across the ballast resistor. Seeing as the circuit is not just the run ballast resistor and the coil, but has the choke in parallel with the coil, the voltage available at the coil would change. How much? Don't know. Probably not a lot. You are increasing the load on the ballast resistor though.  :2cents:

Actually only increase current through the ballast, not the coil.

                 The choke requires full voltage, not reduced voltage after a resistor.

I've read that the Edelbrock electric chokes heat up WAY too fast.  Hooking it up to a reduced voltage source might be a good thing for those. :dunno:

              I've had that issue on a few, I adjusted them on the tight (rich) side and opened up the vacuum feed for the pulloff slightly. Worked like a charm. IMHO it's never a good idea to reduce voltage to any device designed to operate at a certain higher voltage.

most of these engines are run in warm weather anyway so the choke should come off fast
