The Correct Way to Wire an Electric Choke

[Russ130]

While looking through my shop manual from holmes last night I came across the info on the choke heater circuit. I was actually quite impressed with both the simplicity of it and the functionality as well. So I'm going to post a generic way for anyone with an electric choke to wire it up so it works right. First thing you are going to need is an oil pressure switch and this switch should have 2 connectors not one. The reason is because with a single connection switch it makes and breaks contact with ground. With the dual connector it makes and breaks contact between the 2 connectors and does not ground. Ok so you get that plumbed in and you run 12v fused source to it and then from there to the choke. Done!

Why an oil switch? Simple and smart, this way power will only get to the choke heater if the motor is running. This means if your truck or car should stall on a cold morning it will no longer pull off the choke even though the motor is cooling down. The old way makes for a harder restart.

Do not use the little wire off the alternator, that wire is actually a voltage sensing wire and should never be used as a power source. The beauty of this method is that it doesn't matter if you have battery power or hot in run. Well hope this helps.

The problem with forums or any other internet-based communication is that it can be difficult to interpret attitude or tone.  Russ130, you seem to have interpreted some sort of rudeness from Vile, that I don't see at all.  His post seems like nothing more than a quick response directing you to the appropriate past threads on this forum.  His comments merely indicated that there is quite a bit more information available than what he posted, if you perform a search.  I don't think he was trying to make you look or feel like a knucklehead for not searching yourself.  If he were trying to do that, he would have simply posted: "Did you try that little white box with a search button next to it?"  But instead he took the time to share the results of a quick search he performed on your behalf.  And if his response didn't help you because you had already found those threads, just say so or post a followup question.  I think you have let yourself get offended way too easily.

Is this your normal reaction when someone helps you out by searching for information for you?  You have a PM!

[VileZambonie]

What did I miss?  I simply posted that there's been lots of threads on this and provided a few links. Trying to be helpful but if it was taken the wrong way for whatever reason just know it wasn't a lash out at anyone or the original poster.

Glad I missed it. Dont like drama, I deal with it enough with my youth group.

[Russ130]

No problem, my bad. I just ran into a similiar response recently in another forum and that response was truely snotty. Guess I lashed out at Vile thinking he was being the same way.  Again my bad and I'm sorry I behaved that way.

lol I've done that b4 just for having a bad day i took it out on someone who had nothing to do with it

Do electric chokes operate on:

a) heat?

b) time?

c) both?

d) or something else?

c

Electric current passing through the bi-metal coil, causes it to heat up and expand at a certain rate.  It has nothing to do with engine temp, but rather the temp of the coil.
