Hey guys, picked up a pretty nice black knight.
Didn't work, but turns out, the coin door connector was shifted one pin to the right causing the coin door switch (the one that knows if it's closed) to put the game in diagnostics mode.
Next up, the lower flippers just dont' feel right.
All flippers appear to be completely rebuilt with new parts, except one has an older coil.
Adjusted the eos's no notable change.
The uppers seem strong, but it's such a small area it's hard to tell.
Cross referenced the coils with the ones marco sells for them (out of stock) and the numbers match.
No capacitors on the lower coils, should there be?
Every flipper measures 38v
Game has a rottendog mpu.
I checked for the "mushrooming" people seem to discuss for the coil stops, didn't see any.
The other thing is the top left flipper coil buzzes pretty badly sometimes, other times less but it's always there.
No bind in any of the components and parts are tight and work smooth. RESOLVED SEE BELOW
Any insight would help.
There is always a chance that i'm expecting too much from the lower flippers. This is the only game older than space shuttle I've owner to date.
The left ramp is possible, it just takes a precise shot.
