have a 1986 175 and just swapped switch boxes. it came with the 1a box and switched it to the 12 .
The original problem at mid throttel and taking off it was
Dropping a cylinder. Now that I put the new ones on I have no spark.
Any suggestions? To check if im getting voltage to the box when the key is on which terminal
Should I check on the top row of 4?
