Hello,
I have a Coats 1001 wheel balancer which was working perfectly for the 9 months that I've had it up until now. I was in the middle of using it a week ago and was on my second tire when the numbers on the display ended up all lighting up and staying lit. They are 7 segment displays and all 7 bar's were lit up all at once across all of the LEDs. When I hit any of the balance buttons the machine spins like normal but the display never changes. During a normal operation, the LEDs showed 0's on the display rather than all of the bars being lit up and then go dark during the spin and then after the spin show the balance needed.
I took the top cover off and ran a few spins and noticed that during the very last part of the balance cycle when it's slowing down an arc was being produced in the wiring. I turned it off and found a loose spade connector. I crimped it shut and made a good connection again and no more sparks were flying. I then shut the machine off and then after 2 hours tried again and it was working properly. So I figured that that was the issue.
I'll also note that today when I went to use it, it was working fine, and then all of a sudden the right hand display showed about 3 of the bars and the rest were blank, and then all of the display segment panels were dark. I ran a balance and nothing turned on. Then I cycled the power and it went back to the full 7 bars per display again. So clearly not working.
Does anyone know why my machine is doing this? Is there a common circuit board issue that I need to get fixed? Does anyone have a repair / schematic etc? Any thoughts or trouble shooting I can do to help you determine what the issue is?
Thanks!
