6. Use a small jumper wire (e.g. paper clip) to short the ground and signal sockets with a “short-no short” motion.
Each time the short is made, the total volume value should change by increments of one or more.
7. If the Flow Meter (Hz) value stays at zero, disconnect this section of flow meter extension cable and repeat this
test at the next connector closest to RCM - Sprayer ECU. Replace defective cable as required.
8. If all cables test good, replace the flow meter.
9. After testing is complete, re-enter correct meter cal value and units.
