I have read and read. Googled and googled.. But still no spark, I have a 3 cylinder 65 hp merc thunderbolt. I have replaced the harness, checked all wiring(replaced all bad) I have correct voltage across my power block.. I have ran the Cdi tests to check voltage.. Everything is good. But when I connect my coil pack to the green I lose all voltage to the green? What could the problem be? I will have serial number and all tomorrow, I have been working on this motor for some time and I have cleaned carbs, replaced fuel lines, replaced damaged wiring... I am finally hunkering down and posting. Please help, yes I know I'm doing a repost like many other of the 650 thunderbolt no spark post but I have yet to find answers..
