1985 Merc 150 hp v6 outboard no spark

[Mike Schilling]

I am having a problem. I replaced the jets on my engine and the oil line from the injector as well. When I reassembled, there is no spark to any of the plugs. There are two black boxes that control 3 cylinders each.I doubt they both could go like that, so assume there must be a broken wire somewhere. I checked kill switch on control and it seems to be functioning. Is there something simple I'm overlooking? I do have a SELOC manual, but most items say test by substitution. Is there a common wire that may be broken?
Is there a no spark troubleshooting flow chart?
Thanks.

Did you check to see if you accidently tripped the emergency kill switch?

I did check the kill switch, and it tests fine. I do have a Seloc Mercury 1965-91 manual, but there is not much troubleshooting when it comes to no spark on any of the solid states.

Disconnect the wiring harness and jump the stater solenoid.
