Hi, looking for help again on my Hi Dolly.
The Roto target scores correctly, for all numbers, but only pulses the 0-9 unit (with the bell) one less than it should, so 4 times for the 5 target (but adds 5 to score), 3 for 4, etc and none for 1 (again, the score reel moves 1 correctly). This occurs regardless of left or right roto target switch, and regardless of first or second player.
Here's the relevant part of the schematic.
I have checked all the score motor switches and "appear" good. I figured easiest test is on the 5 target (my red "1" above) as then simply the 1A should fire 5 times (red "2") until 4C Opens (red "3")
But when I manually turn the score motor, with a meter on 1A, I notice that 4C closes just before the final close of 1A. As far as I can see, all the score motor switches are screwed in tight, clean, etc and nothing looks obviously wrong?
Photos of score motor:
Starting position, 4C closed (red arrow)
Just before motor comes to rest point - 4C opens (red), but 1A firing one last time (blue - the switch is not visible its on lowest row of motor)
As usual I must be missing something simple/stupid! Ideas?
