2 Unscrew hexagon nut of accelerator lever, remove
lever.
3 Loosen 2 hexagon screws. Remove accelerator.
08.01 ill.1
Throttle potentiometer B13 (accelerator)
(= connector X13)
In case of defective potentiometer accelerator B13,
service codes 23, 24 or 29 will flash.
NOTE: First check cables and
connections.

approximately 1,2 kOhm resistance value switch to
infinetely after moving throttle lever from idle position.
Switch contact should open within the first 10% of
throttle lever (pedal) movement.
R2 Resistance between terminals 5 and 4; 1,2 kOhm
R3 Resistance between terminals 5 and 2; 2,2 kOhm
for normal position of potentiometer accelerator ;
1,4 kOhm at "full speed " max. throttle position.
