Bay Timer/Coin acceptor

[Kool Wash]

One of my bays is reading a quarter as two pulses. I changed out the sensotron but it still read wrong. Changed out the timer and it worked, so I thought. 2 days later and its doing the same thing with all new components. Coleman timer with sesotron acceptor. Can it be the wiring? What should I look for. Thanks in advance.

How did you wire the sensotron?

I followed the wiring from the old one. I double checked it to make sure it matched.

Might try reprogramming timer. My jcc's get goofy sometimes. IM assuming you have BNc timers. Swipe n clean?
