My Jumping Jack works great except for one small issue. 90% of the time the left rollover at the top of the playfield is lit, only 10% for the right rollover. Hitting the pops should switch the rollovers back and forth, but all that happens is the right rollover will only blink and then switch immediately back to the left rollover. Maybe one in 10 hits will the right rollover stay lit.

Someone suggested that the match relay could be the culprit. I haven't investigated this yet. Any other thoughts before I open the head and look around?
