1994 175 two stroke Mercury

Twin 175 electronics work for ignition fire on port engine not starboard, no fire

I replaced stator and both rectifier regulators on starboard engine, all visibly fried due to direct short of yellow wire from stator, still no spark. I switched both switch boxes, cdi, and trigger to starboard engine an dit runs fine

Please clarify, after the switch of the components, what runs fine?
If the starboard engine did not run before the parts swapp, and now it does after the swapp, thwn one of the components swapped is the problem. Restore to original one part and a time and retest each time. That will show you the failing component.
