I've got a '78 Chrysler 75hp with a Magnapower (Motorola II) ignition - Ran fine in the driveway last time I tried, then after going inside for a few minutes, came back and it was a no-go. Crank it forever, turns out there's no spark at the plugs.<br /><br />I haven't done any testing on it yet to see where there is and isn't power - I'll be tackling that tomorrow, probably. All I've done so far is clean the distributor points. Just thought I'd start getting opinions now.<br /><br />Good news is that I've gotten my hands on an entire motor electrical system from a parted-out engine. I'm guessing I'll find that the CD unit is gone, but I'm thinking it could be the coil (or both) as well. I haven't ruled anything out though.<br /><br />I have a Clymer manual for the thing and it only gives testing procedures for the CD unit and coil if you go buy a cd tester and a coil tester. I'm looking for ways to test either or both, using everyday shop tools. Any suggestions? Thanks...
