ELECTRIC SYSTEM

7 - 8

RS125

WARNING

Cutting the jumper across the grey and red

wires of the Rave control unit will set solenoid

actuation threshold to 7,800 rpm.

• Check that the piston moves freely.

• Start the engine and keep it at idling speed.

• Measure resistance across the wires using a tester:

Correct reading = 2.2 Ohm ± 10%.

Key:

1 – RAVE control unit

2 – RAVE solenoid

3 – Flywheel / regulator

• Measure voltage across the solenoid wires with a

tester:

Correct reading = 11.5 ± 1 V at idling speed during a

one-second (only) pulse; after this initial pulse, reading

should stabilise at 5.5 ± 1 V D.C.

13. Safety diode

(stand, neutral, neutral light, starter relay)

Diode test

• Disconnect the (white) two-way connector (4).

Check diodes for correct operation as follows:

1 2 ... 173 174 175 176 177 178 179 180 181 182 183 ... 193 194
