These EME units are hard to diagnose in situ , "drive train errors are often attributed to a failed EME" when in fact a simple gearbox position sensor/actuator has failed.

Skem5 logic drive phase - duty cycle/load bench/earth leakage testing at 300 per unit.

Coolant leak down testing plus resealing service.

Repairs from 750 to 1450.
