Hi.
I've confirmed there is nothing coming out of a new CDI coil.
How shall I trouble shoot between the ignition power pack (Oooohh, Shift Assist Module, oooooohhhhh, fancy...) output feeding the coil and the power pack's (Shift Assist Module's) input signals?
Thanks,
J

If I put a lead out of the coil, I get nothing. That is before the distributor. How are the points affecting something upstream?
Looks like I don't understand distributors. If this were an outboard, I'd be looking at the switch box.
Thanks,
J

No kidding! I thought the coil just puked energy.
The points feedback and release the coil......
I thought the points released to the rotor tip.
Thank you,
J
BTW, with the ignition in the on position, I did measure over 8 volts on each wire feeding the coil.

File the points, use a dwell meter to set the dwell. Then set timing.

If you can't get a dwell reading, your points need filing or the condenser is shorted

Service the points
