I read many posts, and it appears some of the solutions to the codes were replacements of the Stop Lamp switch (S9/1) and the Starter lock-out/backup lamp switch, AKA Neutral Safety Switch (S16/1-3).

JimF's website provides a wealth of helpful information.

Harness will be rebuilt/replaced in the next couple of months.

What other solutions/troubleshooting techniques have been tried to solve the codes above?
