Static time electronic Ignition
An earlier post a while back I was asking how to static time a Dyna S igniton in a 1974 shovel. This is what I did. I rotated the flywheel so that the Line was directly centered in the inspection hole. I then connected a test light to the blue wire on the coil and grounded the probe. Finally I rotated the advance mechanism clockwise. This turned the light off. When turning the advance mechanism back counter clockwise I adjusted the ignition plate so that the light would come back on just when the advance mechanism ends its travel. I hope this is correct. it starts good. I thought however it was the other way around where when you turned the advance mechanism clockwise the light would come on.

According to Dyna S instructions this is what I should do.
1. connect a test light to the blue coil wire
2. rotate the engine until on front cylinder compression stroke
3. remove crank case plug
4. turn on ignition
5. While holding the rotor in the advance position with the flyweights against their stops (counter clockwise) slowly rotate the engine forward until the test light becomes bright. The advance mark shoud be centered in the whole.
I have done that with the exception of I put the advance mark in the hole first then rotate the rotor until it just stops counter clockwise. I turn the plate so that it does that. The problem is the light is on all the time until I bottom out the rotor at its stop and the light goes off.
So am I right or whats going on here

Can't speak to that.
I check them by having plugs out and grounded, key on, engine rolled to Advance mark [double check you are on the Advance mark for your engine and you are on the compression stroke of the front cyl]
Once crank is on advance mark [in the inspection hole] I turn the Mechanical advance unit. If the plugs Fire at the absolute limit of Advance unit travel...It is Correct.
