Diode Modules
2.1 Method of Replacing The Inverter’s Power Transistors and Diode Modules
[Decision according to continuity check by analog tester]
■ Before checking, disconnect the electric wiring connected to the power transistor and diode module.
2.1.1 Power Transistor (On Inverter PC Board)
(Decision)
If other than given above, the power unit is defective and must be replaced.
Note: If using a digital tester, ∞ and continuity may be reversed.
