4) With small jumper wire (or paper clip), short between the 2 o’clock and 6 o’clock
sockets with a "short-no short" motion. Each time a contact is made, the TOTAL
VOLUME should increase by increments of 1 or more counts.

5) If TOTAL VOLUME does not increase, remove the section of cable and repeat test
at connector next closest to Console. Replace defective cable as required.

2 o’clock socket location is ground.
10 o’clock socket location is power.
6 o’clock socket location is signal.

VOLTAGE READINGS
1) 2 o’clock socket to 6 o’clock socket = +5 VDC.
2) 2 o’clock socket to 10 o’clock socket = +5 VDC.
If a +5 VDC voltage reading is not present, disconnect
the Speed Sensor cable. If the Flow reading is
restored, Test the Speed Sensor cable per Appendix
"PROCEDURE TO TEST SPEED SENSOR EXTENSION CABLES".
