Electric choke power wire with Firecore

[Dino]

I know most tap into the blue wire from the ballast resistor or voltage regulator, but I don't have a ballast resistor and would rather not tap into the regular wire.  What's the next best place to tap into.  Any reason I can't hook it up to the Firecore coil?

[Dino]

I just realized the coil has keyed and full 12v so that's out.  I guess I'll have to run a wire inside to the fuse box then.  Dammit...

Thats what I did........

[Dino]

Yeah it's probably the best way to go, I just didn't want to mess with the glove box.  I really don't want to pull it out so hopefully I can reach it as is.

[Dino]

Fuse box is out, way too much work to run  a wire that will likely be only temporary.  I need something in the engine bay.  Any ideas?  Can I tap into the wiper wiring maybe?

[Dino]

Found one, there's a green wire going to the wiper motor that is keyed only.  That'll be a good spot for now.  I'll run one to the fuse box if the carb and choke stay.

FACTORY sourced the choke from blue RUN circuit ( ballast/regulator ) so WHATS THE PROBLEM WITH IT ?

I don't have a ballast resistor.  The Firecore system eliminates it.  I used the blue wiper motor wire, not the green as I previously stated.

so connect it to the blue wire in the RUN circuit that would have connected to the resistor..12 volts is 12 volts no matter where you tap it into. The problem with connecting it to wiper motor is that is also hot with key in ACC as well...

The blue wire that used to go to the ballast resistor is tied in with the brown though because that's what the coil needs.  I don't think I can hook into that one.  I disconnected the choke for now as it seems to start fine without.  If I decide to keep this carb and choke I'll run one from inside.

Maybe you don't have ballast, but the source is still there since is the same you use for the REST of the engine, no matter what ignition are you using ... YES you STILL can take the power from there. Remove ballast doesn't affect to the rest of engine devices, but just the ign

Advice... keep using same source I'm saying. No matter which one you choose, former ballast spliced to feed the new ign system, or regulator.

IF YOU WANT and even better way to source the choke! there are oil senders with built in switches, designed just right for that. Won't feed the choke untill senses the oil getting the sender, meaning with this, untill engine is started and running. They are three prongs... sender, 12 volts in, 12 volts out. The only detail is they are AS FAR I RECALL for idiot lights clusters. Would need to use the other provision on block to fit it

[A383Wing]

yes, you can hook it to that one...it's the same if you had a ballast

[Dino]

So it doesn't matter that the wire is both keyed 12v and continuous?  I thought I wasn't supposed to tap into the coil wire but if I can then this will be a quick fix.

The only time you don't tap the coil wire is if there is a ballast present.

Ohhh well that changes everything then.  I'll reroute the wire to the coil.  Thanks guys.

Coil gets the power from IGN1 ( RUN ) circuit same as the choke must be, and regulator is, ECU and everything else... JUST that the coil gets the power through the ballast and not the rest, but everything including coil comes from same source

the reason why not to feed anything from coil WHEN BALLAST IS PRESENT is because will change the ballast performance, overheating it without need for that due the extra load being taken but not actually requested by the coil.

however if you remove the ballast ( which ever the reason is ), the coil source becomes in just one more device to be sourced from same point with nothing special on that

Just systems like MSD ( multispark discharge ) won't allow you to splice power from any coil source, since is directly sourced from Module in both leads, not anymore from Ign1 ( Run ) circuit on + lead

[Dino]

And here I thought I shouldn't use it because it would be bad for the choke!  Thanks for the explanation Nacho!

I have the Firecore and no ballast and i connected the choke to the blue wire, works fine.

as long as it's battery or charging voltage, you will be fine
