Why does older drive give transistor short circuit fault now that trying to reintialize after putting back into system?

If the drive date code is older than 9626 then the control wire tube is too short which sometimes when running the wires when reach down and pull up, you may unknownly also unplug current sensor 3. This makes the drive think there is a high current and display transistor short circuit. Need to plug current sensor on T3 back in.
If this is not the issue, additionally may want to refer to Service and Troubleshooting manual VD0C06S701 or VD0C06S702 for further possibility since may have an inverter bridge issue that need to isolate or possibly a bad motor or output wiring.
