Ignition Module Pic-Please Look

[Scoobum]

Please tell me this is the problem...just noticed it swapping it in.

The epoxy is breaking down.

[larrym]

That would be my guess.

I went with the other Delco unit I have here. I'm bringing along another aftermarket unit to try as well.

[Steve Wood]

Doesn't Dan have one you can try?

Steve i have a Type II ignition.

I don't like that the wire looks like something was pressing on it and right in that area it look like little deposits of metal or metal breaking thu the encapsulement?

Looks to me that the gasket has failed as well as the epoxy starting to break down.

If you've ever seen the insides of a module without the potting material its just a circuit board similar to the insides of a transistor radio. The potting material is there to protect the electronic components. A crack in the potting material alone should not be a problem UNLESS the crack is letting moisture get to the board, which to me looks to be a little damp. Or the board or soldered joint is somehow cracked and is telegraphing through the potting material.

daveismissing brought up a great point about the kinked wire and what looks like metal breaking the surface of the potting material. Any metal to metal contact there would certainly be a problem. Normally you would see evidence of arcing on the potting material.

Heat is the number one cause of module failure. If its a heat related issue the potting material usually tends to get tackey.
Nevertheless, I'm glad you found the problem Brad. Look me up if you ever get down this way

to add to what he said, we also know that the module can short out when the terminal blade is bent such that it gets pushed into the potting compound when the pack is assembled and it kinda looks like it might be close to doing that at the funny looking wire

Always wondered what was under the potting material...tha nks. Next question I have is this. So what's the difference between the NA module that's in the car now...and it's turbo counterpart?

[daveismissing]

I'm starting to wonder about this as well. The type II coil/CCCI we use come out of normally aspirated- do they not?

[TexasT]

I thought there were some on centuries and some of those body style in olds Ciera maybe

One thing we know is that the turbo module is the only module that will work with the caspers coil tester.  The others do not fire at all when connected to the tester
