Electric choke 12V source

Other than the Ign spade on the fuse block, is their another source that I can use for an electric choke hook up? The previous owner has used the ign spade for a couple of items that I haven't ran out yet. I think it is being used for an after market radio.

Thanks;

Tony

Re: Electric choke 12V source

12 volt to the wiper motor is a good source. ive had good luck hooking them to the alt light wire that exites the field that goes to the alternator. that way the choke doesnt open with the key on

Yes, this is another place to do it. It has been covered many times, too. Might do a search on it here.

Re: Electric choke 12V source

Is this a Holley electric choke? If so, I would NOT recommend connecting it to the wiper power wire. The wiper motor is "hot" when ever the key is on OR in the ACC (accessory) position. So if you have the car off, but listening to the radio for example, your choke is on and Holley's need the car running to cool the element or it will overheat and burn up.

Never connect anything to the alternator field/relay (blue and white) wires. These are not meant to carry loads.

ive hooked dozens up to the light wire. gm did it this way from the factory on cars built from the late 70,s to the eighty's. those cars had a choke light that would glow when the diode trio went bad. you can also use the wiper wire and use a factory oil pressure switch so there is no current untill the engine runs

I've always used the hot side of the coil.

Sorry, yes it's a Holley choke.
Well I decided to convert to an HEI ignition, so in the process I removed the harness, removed the pin connector from the harness and installed a new connector to include the HEI wire and also a choke wire. Works great and looks like a part of the harness.

Again, thank you all for the input, it all helps.

Re: Electric choke 12V source

make sure you have batt voltage while its running at the hei term. the added amp draw might cause a voltage drop. ive never hooked them there but as long as the circuit will support it it should be ok

Re: Electric choke 12V source

Been a long day, forgot to mention the pin I replaced is the source that feeds the IGN spade on the fuse panel.

You should never use the coil! That is a 9.6 volt feed, not a full 12 (unless using HEI), but the worst problem is that it is an unfused circuit. If the electric choke ever dead shorts (which they have been known to do), it will totally burn up the dash and engine harness. The choke should always be on an ignition only fused feed. Do not use an accessory feed, only ignition.

Yup, I have it on the IGN fused feed.
