Hey Everyone,

My Pat Hand has had a consistent issue when stepping down the bonus at the end of the ball. It still counts the correct amount of bonus so I've kinda been lazy about fixing it but now I'm digging into it again.

On single bonus the stepper is supposed to count down in steps of 5 (IE full 10k bonus would complete in 2 cycles of the control motor) but instead only counts down once per control motor cycle. This is the double bonus behavior but it correctly counts single bonus.

It does this inconsistently though - it will count 3 or 4 in a cycle, then 1 the next cycle, then get all 5, etc - I tried correlating these to contacts on the stepper motor but it's random

Double bonus works perfect.

I've tried cleaning the double bonus relay and checking all those contact/solder joints - as well as completely rebuilding the bonus stepper.

Any help here would be greatly appreciated

Went ahead and double checked that one and that stack in particular, no such luck - gave it a good cleaning and verified it's adjusted properly, solder looks good but I haven't used a test light or anything.

Here's a video of the behavior

It ended up being the end of cycle (?) switch on the bonus unit - it's supposed to remain closed while there is bonus left but the vibrations were knocking it loose as it wasn't adjusted tight enough.

Thanks everyone for your help!
