Hoping that someone can give me a suggestion.

On my WHO Dunnit? (W?D) my coin door stopped giving credits when a coin is inserted.

I have all of my machines set to take tokens and it worked fine for about four months, all of a sudden the credits stopped registering. It makes the noise acknowledging a coin was inserted, but it doesn't give the credit on the screen.

I will note that I am having trouble with the spinner switch. The switch started having trouble about two weeks BEFORE the credit problem started, so it might be related... or it might not. I can't really see how it would be, but I guess it is a possibility.

I have a new switch on order, but wanted to see if there were any other suggestions I could try while I wait for it to arrive.

Thanks!
Chris

Spy,

Yeah... duh, you are right. I should know to check the switch matrix. The spinner is on Flipper Grounded 5 and the Service Credits are on Dedicated Ground 5.

That would absolutely make sense that the spinner switch is causing the problem. I guess when it started it was intermittent enough that I didn't notice it, but as the switch continued to break down it became a constant on the credit circuit.

Sometimes I really feel stupid working on these machines. Thanks for the illumination!
