Hi Art, my name is ***** ***** I will be helping you today.
Which model engines do you have?
You wrote that you swapped sending units between the engines. Have you tried swapping the tachs between engines as well?
It looks like you read my reply, are you still with me Art?
I don't work on those engines. I will opt out and leave this question open to the community. Good luck!
