Boom Shutoff Signal Test
Figure 35:
Disconnect the VCM extension harness (6-pin Deutsch connector) from the VCM.
Turn on the boom section shutoff switch for the VCM being tested.
• With the engine of the machine running, use a voltmeter to observe that there is a 13.5 VDC
between pin 2 and pin 3.
• With the engine of the machine off, there is a 12.0 VDC between pin 2 and pin 3.
Make sure that the polarity is accurate by looking at the positive voltage when the red (positive) probe
is connected to pin 3, and the black (negative) probe is connected to pin 2.
If there is no voltage present, do a check of:
• The 80 A circuit breaker at the machine battery
• The 15 A fuse on the VCM extension harness at the Gateway hub
• The voltage at the hub
• The PinPoint
™
battery harness connections
• The boom shutoff switches
For a VCM to spray, there must be 12 V on pin 1 (constant power), pin 3 (boom signal), and pin 6
(key switched power).
