Quoted from rottenrobert1313:
I couldn't resist any longer. After I checked and replaced a few of the Fuses I powered up my medusa. She works but the lower right pop would fire intermittently. I checked to see if the switch was closing with vibration, but that wasn't it. Now it doesn't work at all. Any ideas?? The plunger of the coil moves freely in the sleeve so I think it's fine.
Again I'm new to this hobby so I'm hoping it's an easy fix.
You'll see a small capacitor on that pop bumper's switch. It might be shorted. Clip one side and see if it stops firing randomly. If so do yourself a favor and pick up a batch of replacements. You can get them at Radio a Shack in a pinch. I think they are 1/2 microfarad.
