- Confirmed the customer's complaint and found the engine ran rough. Inspected the air intake system and the fuel system, but found no faults. Connected a spark tester to the ignition coil, cranked the engine, and found the coil did not produce a steady spark. Attached a lab scope with an inductive ammeter to the ignition coil control circuit, cranked the engine, and monitored the ignition coil primary amperage waveform on the lab scope. The ignition coil primary amperage waveform monitored on the lab scope indicated the ignition coil was shorted. These test results verified the ignition coil was faulty.
