Quoted from tfduda:The start up seq sound like it is working normally up to the point that the 100k stepper goes from -1 to zero position. Does the circuit that accomplishes this step (that is, the one to the 100k step up coil that closes via contacts on the 10k stepper when it steps from 90 to 0k) go through the 100k relay (M-relay I assume)? Can you upload this part of the schematic as well as the part that shows the 100k relay circuit?
Otherwise, it sounds like the machine works normally otherwise—I assume this means that when the 10k stepper steps from 90k to 0k that the 100k stepper steps normally and the 100k relay doesn’t stay engaged. Is this the case?
Thanks for the replies.
when the 100k stepper goes from rest position (-1) after the 10 k rests, it stops on zero but the M relay energises and stays pulled in. If I manually roatet the stepper finger off the zero rivet and to the next position, the 100k coil de-energises. Its a bit strange since the contacts that energise the step up are open at the zero position as far as I can tell. I will upload schematics, I'm not great at reading these and with this fault I have been all over the schematic trying to work it out.

So when th 100k stepper goes to zero through the 10k stepper and stops at zero the m ( 100k) relay pulls in and stays energised.
The only way I can get stop it , is to move the 100k stepper arm two notches to the right or remove the earth wire from the 10 k stepper unit( found this out by accident).
Have attached some pics of schematic.
I have also put up pic of 10 k but which has a set of contacts on the rt side that are always closed lol x rpt when the 10k coil pulses. These switches were open when I first looked at the game and it appeared there was an actuator arm missing as the switches did not open or close at any time. I had to rotate the switches so the drive arm on the coil actually opens the switches when the coil pulls in. I guess this is what needs to happen looking at the schematic
