Cummins-Onan QD error code SHORT CIRCUIT (QD 3200)
Warning message: a connected appliance probably has a short circuit. AC output voltage is turned off but the engine is kept running to cool the generator set. QD 3200 (HDZAA) - this inverter-type diesel shows TEXT MESSAGES on the remote Operator Panel display, not the blink codes of the QD 6000-10000 '(QD)' entries. Warning and fault messages, once cleared, cannot be retrieved; to clear faults turn the display off/on.
What to check, and in what order, is in the app. A step-by-step flow walks this code with the pass/fail measurements, wiring schematics and procedures that go with it, and it works offline in the bay.
