B3 - B4:

Normal Operation
The DC/AC inverter receives 12 volts DC on circuits 3025 (YE/LG) and 1003 (GY/YE) and is grounded on circuit 57 (BK). The incoming DC power is internally converted to 60 cycle 110 volts AC power that is output to the AC powerpoint on circuits 432 (BK/PK) (power) and 464 (BK/PK) (neutral). If a fault in the system is detected, the LED flashes when the key is in the ON position. The LED continuously illuminates if the system is operating correctly when the key is in the ON position.

Possible Causes
- fuse
- circuit 1003 (GY/YE) open
- circuit 57 (BK) open
- circuit 486 (BN/WH) open
- circuit 472 (LG/WH) open
- DC/AC inverter
- AC powerpoint
