Hello,

My motor is a 99 Johnson 225 Looper. I've had a ground issue since putting this motor on my boat, but I think I have that figured out ( it was a bad harness). I can start it now but my key switch still does not turn it off, and I now have a soft popping noise when it runs. Any ideas what this is caused by?

Thanks,
Duke1
