💉 Vehicle had just been serviced and had been left running for approximately 20 minutes when it cut out without warning. Fault was purely coincodental to its recent service.
📞 After several attempts to diagnose and restarting even with easy-start, the customer gave up and called us.
🧠 Knowing the engine is actually a rebadged Cummins ISB4 engine from its other career paths, we got to work with a Cummins wiring diagram.
🔌 It was quickly established that even though the main 24v feed for the engine ECU was present on a multimeter, a very simple bulb test proved that the circuit could not carry any current.
🔪 After splitting the harness just a short distance from the ECU, the problem became apparent.
🩹 Repairs carried out and vehicle returned to service.
