with the pointer. If the mark is to the left of the pointer the
ignition is too far advanced. Slacken the distributor and turn
slightly anti-clockwise to retard the ignition until the marks align.
If the mark is to the right of the pointer then the ignition is too far
retarded. Turn the distributor slightly clockwise until the marks
align. When the marks are correctly aligned, securely tighten the
distributor clamp and re-check the timing. Stop the engine.
5. Disconnect the "strobe" light and refit the vacuum tube.

Starting system
The starting system comprises battery, ignition switch, solenoid and
starter motor
(Figure 5) . Rebel models can have either the 35G (early)
or 35J (later) type starters fitted.
If the starter fails to operate when the ignition is switched on then the
components should be systematically checked to diagnose the fault.
Examine the starter pinion which can become jammed in mesh with
the flywheel ring gear. It can be released by turning the square end of
the starter motor shaft in an anti-clockwise direction or occasionally a
sharp blow from a hammer on the casing.
Check the battery is in good condition and fully charged and that the
terminals are tight and free from corrosion. The condition and security
of earth braids is also important, particularly the braid between the
chassis frame and gearbox casing adjacent to the rear gearbox
mountings.
The starter solenoid could be faulty. When the ignition is switched on
and in the start position the solenoid should click and the starter
"bendix" gear engages with the flywheel ring gear which makes a
distinctive sound. If this is not apparent a faulty solenoid could be
indicated.
If the components of the starting system are found to be functioning
correctly this would indicate that the fault lies elsewhere in the
ignition or charging systems. Starter motor testing is detailed below
Bench testing
Remove the commutator end cover from the motor and check the
brushes for wear and replace if necessary.
Measuring light running current
Clamp the motor in a vice and, using a 12 volt battery. with a moving
coil ammeter of suitable range, check the light running current and
the armature speed. Always use heavy gauge cabling for this test.
Under light load the motor should run freely with a current of 45
amps (35G starter) at 9,500-11,000rpm or 65 amps (35J starter) at
8000-10,0000 rpm. The test only proves that the motor functions
correctly when not at its normal operating load. If, on refitting the
motor, it again fails to crank the engine an internal fault is indicated
and a replacement motor will need to be fitted.
Starter motor specification
35G
Lock torque 1.02kg/m (7.4 lb/ft) @ 350 amps
Running torque 0.64 kg/m (4.6 lb/ft) @ 257 amps
Light running current 45 amps @ 9,500-11,000 rpm
Brush spring pressure 850gf (30 ozf)
35J
Lock torque 0.97kg/m (7.0 lb/ft) @ 350 amps
Running torque 0.61 kg/m (4.4 lb/ft) @ 260 amps
Light running current 65 amps @ 8,000-10,000 rpm
Brush spring pressure 800gf (28 ozf)
Note: The later 35J starter motor is not a direct replacement for the
earlier 35G model as the through bolts on the starter motor protrude
from the end of the motor so require a different gearbox casing to
accommodate them. The earlier 35G motor can be used on any
vehicle but to fit a 35J to an earlier car the bell housing needs to be
machined to clear the through bolts. (

Charging system
The charging system comprises a battery, dynamo, regulator,
alternator (vans only) and ignition warning light.
It is important that the charging system be kept in good working order
because the ignition, starting and lighting systems depend on it. These
systems will be rendered inoperative if the battery is in an extremely
low state of charge. The electrolyte level in the battery must be
