(e) If voltage rises from 0V to 7V in the sequence shown, the control system is okay. (f) The voltage could rise anywhere between 0V — 8V before the vehicle reaches 10 km/hr or 6 mph in first gear. The voltage jump depends on what percent the throttle valve is opened. This is a normal reading. Above 10 km/hr or 6 mph, the voltmeter indicates the current gear. NOTE: Determine the gear position by a light shock or change in engine rpm when shifting.
