There’s a certain pattern of how the needle moves: At the beginning of milking needle doesn’t move at all. After the 2-minute timer times out the needle moves very fast in the range of 0 to 5 psi.

The key here is that the gauge returns to 0 inbetween slugs going thru the sensor, and it gradually climbs again. If a machine comes off early and assuming the whisker valve is the problem, the gauge climbs to 5 and 7 and 10 psi and when a slug hits the bell needle it goes to 0 but then instantly back to where it was, let’s say 12 psi, instead of climbing gradually from 0. There is the problem. Replace whisker valve. For the more technically gifted of you, here’s what’s happening inside the grey timing circuit: With everything working honky-dory, i.e. normal operation The air coming from the D-Restrictor gradually pressurizes the grey circuit. When a slug hits the bell the whisker valve opens and releases a small amount of that air. Unfortunately, no matter how fast the cow milks, the whisker valve never releases all of the air coming from the D-restrictor and the pressure gradually increases until the machine comes off too early. How to solve that problem? Add the EV-125 Quick Exhaust on top of the timing chamber. Now, whenever the whisker valve opens to release that small amount of air, it cause a pressure drop in the grey circuit. That pressure drop in turn causes the
