Ignition Module

[Capt Bob]

I have a 1990 Johnson 4.0 Deluxe that produces no spark to the plugs. Is there a testor for this CD2U ignition module?
If so would most service depts have such a testor. Any suggestions on testing this unit otherwise, since if I purchase a new one and that is not the problem, then I am out 100 bucks !!
Thanks, Capt Bob

Yes dealers can test ignition system on it and find problem.
