Method of Replacing the Inverter's Power Transistors Modules
Checking failures in power semiconductors mounted on inverter PCB
Check the power semiconductors mounted on the inverter PCB by the use of a multiple tester.
<Items to be prepared>
h Multiple tester : Prepare the digital type of multiple tester with diode check function.
h Turn OFF the power supply. Then, after a lapse of 10 minutes or more, make measurement of resistance.
h To make measurement, disconnect all connectors and terminals.
