Little Black Box??

[bntcrkfrm]

In the engine compartment mounted on the drivers side Fender well under the Brake Master Cylinder is a black box about 4" x 6" with some electrical wires come from the bottom of it. What is it and what purpose does it serve? Mine has what appears to have been some overheating and some plastic melted on the fenderwell.....

It's required. And attach a pic if you can...

Sorry about that...It is a 1980 CJ5 ...I cant seem to figure out how to attach a pic from my folder. It says Motorcraft on the box #12A199

Searched the Motorcraft #12A199 and turns out it is an Ignition Module. What does it do and why would it be leaking what looks to be melted plastic. Nothing is wrong, Jeep starts and runs fine, no hot wiring smells.

That ignition module takes a signal from the pickup assembly in the distributor and sends pulses to the coil to make the sparks.

BusaDave, Those are the steps I follow to post pics but when I click to upload it comes back as invalid file. There's something not right when saving pics to "My Pictures" folder. I can see the pics but sometimes they will transfer, sometimes they wont. Thanks

The ignition module is needed on a stock engine but there are ways to get rid of it. Do you have an MSD or other aftermarket ignition module? Did a PO install a points distributor?

I assume you are using the instructions at the beginning of that link. You press the button that says "Manage attachments" and get this screen.

Press browse and find your picture.
Then press the upload button. I think some people forget this step.
Before you close the window make sure the name of your image appears in the window.
My image is called upload.jpg and you can see it in my picture.

I haven't seen anything else and I don't believe it's a points distributor

 

[bntcrkfrm]

Yes Dave, I did use that screen and when I browsed, chose and click upload thats when it comes back "Invalid File".

 

[Old Dog]

What size are they? they might be to big.
And you still haven't filled out your profile

There must be something making your engine run.
Trace the minus wire from the coil. That wire must go either to points or to some type of ignition module.

Will do on Friday or Saturday. This jeep is many firsts for me and I think it ran off of pfm (pure f*cking magic)
