Sammy Mr. Magic - need help identifying mystery buttons and switches

[rjlatherow]

Hello all - Just picked up an older Sammy Mr. Magic. I haev it working great except for no sound and the stop buttons not working. Replacing the fude on the stop board causes the light switch to clik off like a circuit breaker- very odd. More on that as I dig into it.

My immediate question here are some switches on the back of the door. there are 2 small buttons and a sliding switch. The buttons are labeled HR and MR on the circuit board, and the switch has N and D in the 2 positions.

I know its not the payout level - that is controled by the momentary switch inside.

Any ideas? Photos in my next post-

I would double check that fuse hasn’t blown again.

With a good fuse I can't turn the lights on. Without a good fuse, the lights come on and it all works except for no sound and no stop. Weird. Also, the fuse doesn't blow but the light switch trips like a breaker. I'll film it in a bit- in the meantime, what the heck do these switches and buttons do??

I have this same machine just waiting to see if the reel stop board can be fixed but I was wondering the same thing about these mystery buttons �� I know that the bottom toggle switch on the power supply is to dump the hopper and I have just put a switch in to replace the key I was Also Wondering if I should cable ties the door switch closed but it plays either way I just can't stop the reels spinning ������ board comes back and it works
