Edelbrock 1400 electric choke black wire melted

Hi All,

I just finished installing a new Edelbrock 7501 Air Gap intake, it is replacing an old Edelbrock C3BX manifold. The intake went fairly smooth and as expected. Once I got it all put back together I fired it up and bam, bright red glowing wire and smoke near the carb... Oh crap#%!&@^

So the Electric choke has two wires a black one that was connected to the body of the carb previously so I left it there during this install and a second wire, I assume power coming from the engine harness, it's red but may not be original so not sure color helps...

So the black wire, I assume the ground is the wire that smoked. My guess is that the electric choke failed and shorted internally? Can't think of what else it could be? Anyway I disconnected the power wire and clipped the charred remains of the ground wire and she fired right up. I timed it and she is running strong?

Any ideas beside what I already said? The current carb is an EGR Edlebrock 1400. I was think about swapping it for a 1405 with Electric choke kit but was going to wait a while until I was sure the intake install was all good. Perhaps this is a sign that I should have done that to being with?

Thanks in advance, this forum is awesome and for the most part responsible for helping me keep my ride on the road.

Re: Edelbrock 1400 electric choke black wire melted

Hey guys, I just thought of a quick follow up question. How can I tell what state my choke is in now? Is it stuck wide closed, wide open... Not really sure how to tell?

First of all...if the power wire feeding the choke circuit was fused (maximum 10 amp fuse as required), the black ground wire would have never "smoked". You need to verify which wire the power is coming from, with a test light or voltmeter, then verify the + and - leads on the choke housing. Connect the - with a short jumper to the carb housing. Connect the + to a fused source, preferably within the ignition switch circuit "on" position. Sounds as though the wires may have been crossed!

Re: Edelbrock 1400 electric choke black wire melted

Is it possible that there is no longer a body ground from the carb through the new intake to the block to the ground straps to the body?

Pull the electric choke housing off the carburetor and inspect it inside and out for a short, use an ohm meter to check it out and the problem should reveal itself.

Re: Edelbrock 1400 electric choke black wire melted

So I did some testing and verified that the + side was connected to ignition hot and that the black was connected to the carb body. The only thing that changed was the manifold, I never disconnected the ground so crossed wires is not a possibility. My old intake was a C3BX which I believe was aluminum like the new one but is it possible that the new one is not providing a decent ground? Should I hook the ground wire to something other than the Carb Body?
