Pinpoint Test
- CHECK THE SYSTEM OPERATION
- START the engine.
- Connect a device with a rating of less than 150 watts to the AC outlet and verify power supply at the AC outlet.
Is power available at the AC outlet to operate the device?
- Yes:
- GO to 2 .
- No:
- CHECK THE LED CONTROL CIRCUITS FOR AN OPEN
- Disconnect DC / AC Inverter C3501B.
- Disconnect AC Outlet C301.
- Measure:
AC Outlet DC / AC Inverter C301 C3501B Pin Circuit Measurement / Action Pin Circuit 6 LYA03 (YE/VT) 1 LYA03 (YE/VT) 4 RYA03 (BU/BN) 4 RYA03 (BU/BN)
Are the resistances less than 5 ohms?
- Yes:
- GO to 3 .
- No:
- REPAIR the affected circuit(s).
- CHECK THE AC OUTLET LED
- Test the diode in both directions:
AC Outlet AC Outlet C301 C301 Pin Circuit Measurement / Action Pin Circuit 4 RYA03 (BU/BN) 6 LYA03 (YE/VT) 6 LYA03 (YE/VT) 4 RYA03 (BU/BN)
Is the resistance greater than 10, 000 ohms in one direction and between 10-20 ohms in the opposite direction?
- Yes:
- INSTALL a new DC / AC inverter. REFER to Direct Current-Alternating Current (DC-AC) Inverter .
- No:
- INSTALL a new AC outlet. REFER to Alternating Current (AC) Power Point .
- Test the diode in both directions:
