Chrysler ignition

[Matthew Pieklik]

Hi all , My project is a Montgomery Ward Chrysler.I don’t know which year because the tag is missing. I going to guess around 1975-76. Anyhow, the coils, Wico X18248. When I test them with my Merc-o-tronics 98, I get a good primary reading. The secondary test open. Plug wire to either lead test open . But when I test for spark , I do get spark on the 98 tester. Is the spark jumping the open in the coil? Both coils are the same. I also see that the laminates for the coils are pinned and peened on. (Must have been Mercury Engineers). I think I would like to convert the wico coils to OMC coils.  If they don’t fit I may look at a coil from a Tecumseh engine. They used wico coils. Any Idea how to get the coils off without destroying them. I’m thinking Dremel tool. New coils at Marine Engine are $168.00. Also , my points are trashed and I have one bad condenser. So I’m going to try the Nova 2 route just to satisfy my curiosity.  So I’m looking for the best way to remove the coils, or do the coils come off the laminates in place? Thanks , Matt.

If there are metal tab on the core like mercury 63 and up the straiten the tab and tap it off.

If you are getting good spark with “open” secondaries it could be something so simple as the connector at the spark plug end is not touching the copper wire.
