901- Engine Warm-Up Procedure / Engine Start
901 - 1 Preparation before Engine Start
901 - 1.1 Checking / Adjusting Gearbox Potentiometer
To avoid damaging the gearbox, the gearbox potentiometer setting must be
checked before running the car on track or selecting gears with the engine
running. If necessary, the gearbox potentiometer can be adjusted as described
below.
Checking gearbox potentiometer voltage
1. Turn on the main and ignition switches
2. Select neutral (N) – ‘gear’ value in display must be ‘N’ (rear wheels
can be easily turned by hand)
3. Selected display page 5 (‘startup’ page) and check ‘gearpot’ value
4. The value displayed should be 1.2 V ± 0.03 V
If the ‘gearpot’ value is outside the permitted range, the gearbox potentiometer
must be adjusted.
To check that the gearbox is in neutral (N) and not between gears, the position
of the shift barrel can be checked. The gearbox potentiometer must be removed
to do this. The groove to align the potentiometer must be set at ‘2 o’clock’.
