I don't know if anyone on this posting has read my postings on trying to resurrect my Hot Spot, but I was having similar issues. Somehow (it was not because I know what I'm doing!) but I got the motor to quit spinning and now have my machine at least "partially" playing.
I just found where/how to set it to free play, so after work, I'll try that.
But things not working:
After the 1st ball drains, it immediately kicks the next ball out (like it should) but then simultaneously goes into "Game Over" mode??? More than likely a dirty relay?
I'm also not getting any sounds, but the sound unit looks to be in good shape, so thinking it's just not getting signals?
As with the other post, any and all help is "Greatly Appreciated"
