intermittent scoring for the pops still persists.
I have cleaned and adjusted Relay B twice with no luck.
I have cleaned and adjusted Relay L and M which score 500 and 1000 with no luck.
I took a look at 4A and cleaned what I could get to (top stack) because all I see is a 4 on the round bottom motor relay.
No idea if the top easy to get to stack is A, or if the lower stack that is hidden is A.
But I'm not sure it would help much as that motor never moves at all during pop bumper hits.
Also another thing we noticed, and maybe this is normal, is that when you activate one pop bumper they both energize at the same time.
Seems like just one should activate at a time.
So during a game they may score perfectly for one or two balls then they will just start popping with no score or chimes for awhile, then magically fix themselves.
None of it makes any sense.
