This last December I had a spark plug wire break so I replaced them with some new ones off ebay supposedly made for outboards. My engine ran excellent after putting them on. 2 months later my power pack goes out. I replace it with a used one, the engine runs great then burns out another power pack 1 1/2 months later. I have now replaced with a new cdi power pack.
I'm now worried that my spark plug wires could be what was causing the power packs to burn out so I have gone back to some old spark plug wires that I have. Is it possible that the spark plug wires could have caused the power pack to burn out?
I checked resistance in the original Johnson wires and they are at 1 while the replacement wires have resistance of 70. I checked resistance on new Sierra replacement wires made for my engine (#18-5231-1) and they have a resistance of 170. The Factory Repair manual says resistance should be close to 0.
I'm completely confused on this spark plug wires now and just want to prevent another ruined power pack. Am I just overthinking this and just had a couple of bad power packs? The engine runs so incredibly good with each power pack before they go out.
Thanks in advance for your input,
Scott
