Hi everyone,

I hope to find some help here that I would really appreciate.

I bought a pretty nice Centrigrade 37 a week ago and I noticed that the sound is different. Comparing to the other EM I already have, the sound seems not working properly.

1- The tens chime plunger does not work when the ball hits any 10 points swithches on the playfied but the score reel works great and add the points. It makes a sound only if I touch the rubber with my finger but the sound is not lound but acceptable.
2- The hundreds chime is working properly .
3- The thousand chime works but the sound is really weak and when it is in action, the hundreds chime pluger moves a little at the same time crating a strage sound.
4- I did a test to each plunger by using the 100s wire connected to the tens chime. It works perfectly! When it is connected to the thousands chime it works great too!
5- I cleaned and ajusted the switches (tens relay and thousands relay in the backbox).

I don't have the schematic and looking for it. I really don't know what to next.

Thanks to those who will try to help me solve this problem.

Best regards,

Denis

Thanks to KenLayton , currieddog for where to find the schematic, goldenboy232 , and runbikeskilee .

I tried what Lee wrote. That solved the problem. The "N" relay (switches adjustment).

Thanks to all of you again!

Best regards,

Denis!

Lee, everything is fine now! It was a similar adjustment with the "L" relay.

Thanks a lot!

Denis!
