Attatched are pics how do these get wired I have a red and purple wire coming out the round coil.
Might help to know what this engine is, that sure looks like a Prestolite electronic distributor. I actually have one of those modules but no instructions on how to wire it. I believe those wire have to be connected to the ignition coil but right off can not find a clear diagram online.
It's a hercules g 1600. Yes it's a prestolite distributor.
After a lot of digging I think I might have the answer. Only thing is seems Prestolite changed the color of one of the wires. They all seem to have a red but the other wire color varies. Yours has red and purple, I have one of those modules with red and tan and I believe I saw one with red and some other color. I can only assume the color of the second wire in some way told someone at Prestolite something about the module. All that said the easy to understand diagram I found shows red and black so I would think of your purple wire as being black! See the attached picture: Red wire being hooked to the + terminal on the coil along with the switched wire from the ignition switch.
Ok that's how I have it wired and I am getting no spark still. When I bought engine this was not connected so I didn't have anything to go by.
Have you adjusted the air gap from relucter to stator? Have you places a test light (grounded on power) to your negative side of coil and checked for pulse while cranking? Lastly, have you checked the coil integrity? Is it shorted or leaking.
Tried 2 new coils tested them and are good. Air gap is good. But no spark
But are you getting a pulse while cranking? If the coil doesn't have any dwell time, it can't build a spark.
While cranking no pulse it never seems to make a ground
Then odds are your pickup is failed. There are tons of aftermarket sources. Just make sure you match the voltage. 6, 12 or 24
Try this, it should tel you where the problem is.
