I have attached the readings I wrote down while trying to troubleshoot my 1976 135hp Evinrude. Issue is intermittent spark, have spark to all 4 cylinders one day, 3 the next day, currently have spark to 2 cylinders only (one bank). I have a new powerpack installed. I have ruled out coils. If I switch the timer base wires, I do get spark to the dead cylinders so the problem is following the timer base wires, however they are ohming out OK. The one reading where I tested from the black/white, white black wires to ground were way off. I do have a DVA adaptor tester. What do you think the problems is?? Thanks
