1992 70hp Force has no spark

[hole in the water]

I have a 70 hp force that was rebuilt about a year ago and we went to go crank it up about three days ago and there was no spark whatsoever. It has a mercury red stator on it and it uses a Thunderbolt Cdi ignition system. Could I please get some advice on where to start testing to figure out what the problem is.

Welcome to iboats.

First, check the safety kill switch lanyard.

Examine all wires to/from the coils, switchbox, stator, trigger, and ground.

Check for resistance between the two yellow wires from the stator.
Looking for 3600-4200 OR 1100-1600 Depending on which stator is in there.

Check the trigger wires for resistance.
white/black wire, to each of the other 3 (brown white and violet).
Looking for 1100-1400 ohms.
