Gary Lewis Posted November 15, 2018 Share Posted November 15, 2018 It is possible that your coil is shorted internally and drawing too much current. So replacing it is probably a good idea. Link to comment Share on other sites More sharing options...

Think I’ll do that. Any suggestions on coil I should get or avoid? Link to comment Share on other sites More sharing options...
1986F150Six Posted November 15, 2018 Share Posted November 15, 2018 Here is what the underside of a new unused module looks like. The resin will get gooey and bubble if over heated. https://i.ebayimg.com/images/g/1tMAAOSwoW1buVsr/s-l1600.jpg Link to comment Share on other sites More sharing options...
Gary Lewis Posted November 15, 2018 Share Posted November 15, 2018 I would go with a Motorcraft, but if you want to go aftermarket I'm hearing better things about NAPA Gold ignition parts than anything else other than Motorcraft. The part number I'm seeing here (Elecrical/Ignition) is D5AZ 12029-A and the Motorcraft # is DG-314. Link to comment Share on other sites More sharing options...
vjsimone Posted November 15, 2018 Share Posted November 15, 2018 Those streaks look like ET's fingers..... Did you squash his hand in there the last time you replaced the module? Link to comment Share on other sites More sharing options...
Gary Lewis Posted November 15, 2018 Share Posted November 15, 2018 Those streaks look like ET's fingers..... Did you squash his hand in there the last time you replaced the module? Good one, Vinny! And I forgot the "which ones to give a miss" part of the question. That would be Mr. Gasket. I won't use their parts on anything. Link to comment Share on other sites More sharing options...
Rembrant Posted November 16, 2018 Share Posted November 16, 2018 Replacement is on the way. Just curious, what IGN module did you go with? Brand/supplier? Link to comment Share on other sites More sharing options...
neoniacin Posted November 16, 2018 Author Share Posted November 16, 2018 Replacement is on the way.Just curious, what IGN module did you go with? Brand/supplier?Just got a new one of the one that is currently leaking. Motorcraft 12A199 Amazon has them. Having a hard time trying to find a motorcraft coil though. Will probably have to go with something else. Unless someone has a source? Link to comment Share on other sites More sharing options...

NotEnoughTrucks Posted November 16, 2018 Share Posted November 16, 2018 Gotta say I have never seen potting material like that before. I have baked a few modules to break up the potting myself. Usually, it weakens and becomes granular. I have never seen semi transparent material like that before and it certainly looks like the source of your leak. It may be possible that someone has been in there before. The purpose of potting electrical components is to protect against the environment, although it also does an excellent job of making the module somewhat proprietary. I would worry about a potting compound that liquefies with heat. Does this stuff melt if you apply heat? Anyways, replacing the module appears to be the correct thing to do.
