Pinpoint Test A: The DC/AC Inverter Does Not Operate Correctly - No Power at the AC Power Point
Refer to Wiring Diagram Set 12 (Escape/Mariner, Escape Hybrid/Mariner Hybrid), Charging System for schematic and connector information. See:
Diagrams/Electrical Diagrams/Diagrams By Number
Normal Operation
The DC/AC inverter receives 12 volts DC on circuits SBP04 (GN/RD) and CBP35 (YE/GY) and is grounded on circuit GD182 (BK/GY). The incoming
DC power is internally converted to 60 cycle 110 volts AC power that is output to the AC power point on circuits HYA01 (OG/GN) (power) and
HYA02 (OG/WH) (neutral).
NOTE: The electrical device that is powered by the AC power point must not exceed 150 watts.
NOTE: If the green LED is flashing, the AC power point may be overloaded, overheated or shorted. Unplug the electrical device from the AC power
point and cycle the key. Refer to the Owner's Literature to determine if the electrical device is appropriate for the AC power point.
This pinpoint test is intended to diagnose the following:
-

PINPOINT TEST A: THE DC/AC INVERTER DOES NOT OPERATE CORRECTLY - NO POWER AT THE AC POWER POINT
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the
connector.

A1 CHECK CIRCUITS SBP04 (GN/RD) AND CBP35 (YE/GY) FOR VOLTAGE
-
Ignition OFF.
-
Disconnect: DC/AC Inverter C2293a.
-
Ignition ON.
-
Measure the voltage between DC/AC inverter C2293a-1, circuit SBP04 (GN/RD), harness side and ground.
-
Measure the voltage between DC/AC inverter C2293a-3, circuit CBP35 (YE/GY), harness side and ground
-
Are the voltages greater than 10 volts?
Yes
GO to A2.
No
CHECK the Smart Junction Box (SJB) fuses 1 (30A) and 35 (10A). If OK, REPAIR the circuit(s). TEST the system for normal operation.
