PROCEDURE
1. INSPECT VOLTAGE INVERTER ASSEMBLY
(a) Measure the voltage and resistance of each terminal from the back of the wire harness connector with the connector connected.
Standard:
| Tester Connection | Input/Output | Item | Condition | Specified Condition |
|---|---|---|---|---|
| 1(IG) - 4(GND) | Input | Voltage | Engine switch on (IG) | 11 to 14 V |
| 3(AC1) - 7(AC2) *1 | Output | Voltage | Inverter operating with engine switch on (IG) | 75 to 120 V *2 |
| 4(GND) - Body ground | - | Resistance | Always | Below 1 Ω |
| 7(AC2) - 3(AC1) *1 | Output | Voltage | Inverter operating with engine switch on (IG) | 75 to 120 V *2 |
HINT:
- *1: When measuring with the tester, AC voltage is generated. Therefore, make sure to set the tester to the AC voltage range.
- *2: Since the AC voltage cannot be exactly measured with the tester, a wide range has been listed for the specified condition.
If the result is not as specified, replace the voltage inverter assembly.
