No Spark Issues Merc 200 20hp

[nbaffaro]

I am not getting any spark from my merc 200. I have replaced the switchbox, rectifier and the trigger. I am still not getting anything. I have tried the spark check method with the spark plug out, with a wire wrapped around it and no spark. I have used a spark checker. I have hooked and unhooked the salmon wire from the kill switch. I am getting nothing. Any ideas?

(I replaced those parts with used parts)

It's always a good idea to test the system and not just throw parts at it. Do you have a OHM meter or DVA?

DVA no
OHM meter- maybe probably a function on my DVM
