I had the same issue and it was a switch on the bonus relay, I think G that that wasn't getting pulled in by a switch on the score motor. If I manually held in the bonus relay the counter fired off like a machine gun 5 at a time.
My recollection of the relay might be wrong, typing this up at work.
What you described is exactly the issue I had. Check & clean the 1C and 2B score motor switches
One of those 2 locations fires 5 times per motor revolution (visible on the motor pulse diagram near the index). The other one is probably the culprit
Quoted from rolf_martin_062:where is the Bonus Unit mounted ? - and where is the G-Relay mounted ?
Correct, bonus unit is on the playfield, G-relay is on the bottom board.
Quoted from rolf_martin_062:I am german speaking - I do not understand "machine went on the Fritz" - my impression is "something non-pleasing".
This means something is wrong, usually unknown or not always able to reproduce the issue. Most likely OP is trying to get the game back to a working state to finish looking at the bonus issue
