Turn the circuit breaker for the battery to the OFF position.
Turn the ECS to the OFF position.
Thoroughly inspect the ECM connectors J1/P1 and J2/P2. Inspect all of the other connectors. Check the allen head screw on each of the ECM connectors for the proper torque. Refer to Troubleshooting, "Electrical Connectors - Inspect" for the correct torque values.
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connectors that are associated with the circuit.
Check the harness and the wiring for abrasion and for pinch points. Expected Result:All connectors, pins, and sockets are completely coupled and/or inserted, and the harness and wiring are free of corrosion, of abrasion or of pinch points.Results:
OK - The harness and wiring appear to be OK. Proceed to Test Step 2.
Not OK - There is a problem in the connectors and/or wiring.Repair: Repair the connectors or wiring and/or replace the connectors or wiring. Ensure that all of the seals are properly in place and ensure that the connectors are completely coupled.STOPTest Step 2. Test the Circuit for the Local Emergency Stop Switch
Turn the circuit breaker for the battery to the ON position.
Turn the ECS to the STOP position.
Activate the local emergency stop switch on the control panel.
Monitor the air shutoff solenoids.
Deactivate the local emergency stop switch. Expected Result:The air shutoff solenoids activated.Results:
OK - The air shutoff solenoids activated correctly.Repair: The problem may be intermittent. If the problem is intermittent, refer to Troubleshooting, "Electrical Connectors - Inspect".STOP
Not OK - The air shutoff solenoids failed to activate. Proceed to Test Step 3.Test Step 3. Check for Voltage from the "ASOS" at the Connector P-C1 for the Power Distribution Panel
Turn the ECS to the OFF position.
Remove wire G708-BK(Black) from terminal "I" of connector A-C90. Install a wire jumper into the connector for wire G708-BK(Black).
Turn the ECS to the STOP position.
Activate the local emergency stop switch.
Monitor the voltage on the wire jumper in terminal I at connector A-C90 of the rigid harness. Refer to Illustration 1 for a schematic of the circuit.
Activate the local emergency stop switch.
Return all wiring to the original configuration. Expected Result:The voltage measures 24 3 VDC for approximately 2.5 seconds.Results:
OK - The voltage measures 24 3 VDC for approximately 2.5 seconds. The circuit is operating correctly to this point. Proceed to Test Step 7.
Not OK - The voltage did not measure 24 3 VDC for approximately 2.5 seconds. Proceed to Test Step 4.Test Step 4. Test for Voltage to the Coil of Relay "R4A" at the Connector P-C2 for the Power Distribution Panel
Turn the ECS to the OFF position.
Remove wire 354-BK(Black) from terminal "B" of connector A-C91.
Turn the ECS to the STOP position.
Activate the local emergency stop switch.
Monitor the voltage on wire 354 at connector A-C91 of the rigid harness.
Deactivate th
