<VV> How to connect electric chokes?

[Sethracer at aol.com]

John - Logically, you would want the chokes to be closed when cold, then to 
 receive power at cold engine start, then, as the coils warm up with e
lectricity,  to open the choke plate, letting the engine return to a regular 
idle. So you  want to supply the chokes with an ignition switched 12 Volt 
supply. The coil may  or may not have that, depending on your wiring. The wire at 
the coil is probably  doing all it can to supply your ignition and shouldn't 
be tapped to feed those  chokes. In the best of worlds, another ignition 
switched 12 volt feed from  the fuse box would work, but that would be a lot 
of work. How about adding a  relay in the engine compartment which would 
lesson the electrical load on the  ignition system and supply a straight 12 volt 
feed from the battery to the  chokes. You would have to find out what kind 
of electrical load the chokes would  take and make sure the relay would 
carry that. Depending on the relay, the  closing circuit should take a lot less 
power than the choke coils. You could  pull that switching circuit off the 
firewall terminal where the coil resistance  feed lives. I am sure you will 
get other suggestions for the feed.

Anyone  have any ideas on how to connect an electric choke on some 2 bbl 
carbs on my  LM Corvair?  The wire was connected to the coil but I’m not sure 
if I  connect to the positive or negative terminal. Many thanks for any help 
so I  don’t fry the coil. Thanks John Gull in Asheville  NC
