measure continuity between the 2 pins. if it's reading shorted then the insulation is exposed in a spot and touching the metal frame.Thank you I'm hoping the coil is what I need
I appreciate it yes this donkey Kong is never leaving my possession thank you that helps motivate me to keep pushing.Stick with it. This is good training. If you plan on owning these games you pretty much need to learn how to deal with this type of stuff. It can be daunting but if you hang in there you will be able to resolve most things, build your knowledge base, and get better at it.
I have a frogger I am jumping into after the donkey Kong is running.Stick with it. This is good training.

I'm working on getting another coil and okay I will try turning that down when I get home today. Question when I turn on the machine the screen scrolls but once I adjust the knobs near the chassis the imagine stays still. Any idea what could be causing that issue?Besides the obvious purity issues that you are having, (I would consider just fixing that with a quality handheld degaussing coil) the screen pot on your flyback is too high because your retrace lines are visible.
Those white vertical lines and that "blue-ish" background will disappear when you turn the screen pot down.
You should be aiming for a pure black background.
