gates are closed and nothing is on the foot switch. When you step on the foot switch with the gates closed, you should
see a closed circuit.
STEP
1. At the Ground Control Module, P2 connector, check the voltage across
pins-16 (orange/red 49-5) and 6 (black 12) is reading within specification?
2. Remove the P2 connector from the Ground Station Module; check continu-
ity of the individual wires in the platform harness. (P2 to platform junction
box),
3. Check continuity of gate switches and foot-switch circuit. (Switches are
wired in series; doors shut and foot switch depressed, circuit will be
closed)
