I took a last pre-snow drive the other day, and on the way back to the house, the truck started sputtering and quit, all in the space of about 100 yds. At night. In a cold drizzling rain. Good fun.

It cranked fine, was getting fuel normally, but it would not run, just popping some when I tried to start it.

This echoes what I remember when the ignition module on my ‘77 M886 failed: the truck was running fine one minute, dead the next, and would not run at all until I replaced that module.

So, I’m wondering how to test this Pertronix— I gotta get this thing off my lawn where the tow truck left it.
