This is my first and only machine.This forum has helped me with all kinds of problems in the past but this is a new problem. The counting number wheels are not always reading accurate. It has gradually gotten worse. Example... May be at 98000... hit something and it just reads 98000,99000,then goes back to 91000,92000,93000 etc but wont change over to the 100000. Does this mostly on thousands and 10 thousands. I have no idea how to fix it. Please advise. Thank you!!

You will find leaf switches associated with the score reels. Clean them by taking a business card and swiping it three times between the contacts when lightly squeezing them.

Take a look at the gap in the contacts while actuating the coil rod by hand. Watch the wheel as it goes to the zero and nine positions. When it opens or closes those leaf switches does it do it dramatically and solid or kind of open and close? There should be a very solid open / close.

A problem that occurs intermittently is usually bad contact due to something not clean or tolerant. Not something blown or broken.

Your ninth position switches need to be cleaned and adjusted. Check here: http://www.pinrepair.com/em/index2.htm#reels
