5 Checking the ignition timing
1 The ignition timing can be checked using a battery and bulb
arrangement connected as shown in the accompanying
diagram. Owners of multimeter test instruments may prefer to
use these, set to the most sensitive resistance scale, as
continuity testers. Note that the easiest way to connect the
probe to the contact breaker assembly is to disconnect the
generator output lead connector and locate the black or
black/white lead to the points.
2 Set the rotor so that the F mark registers with its datum
mark, then adjust the fixed contact so that the points just start
to separate. This will be indicated by the test lamp flickering (or
the meter needle deflecting). Check that the contact breaker
gap is within the tolerance given.
6 Ignition coil: checking
1 The ignition coil is a sealed unit and designed to give long
service without need for attention., The coil is located under the
petrol tank, which must be removed to gain access.
2 A number of tests can be performed using a basic test lamp
6.1 Coil and condenser are located beneath the fuel tank
