3.5.3.
the battery is considered charged at 75% or more. if it failed the load test with this charge it should be replaced. if the voltage indicates a
charge level below 75% then charge the battery and load test again. if it fails this second test replace it.
Charging system (12 volt)
3.6.
3.6.1.
start engine and allow to reach normal operating temperature. switch off all accessories.
3.6.2.
run engine at 1200 to 1500rpm and note meter reading, which should be in the green 'oK' sector (fig.1.H). do not press the load switch.
3.6.3.
switch on head lights and heater fan (highest speed), meter reading should remain in the green 'oK' sector.
3.6.4.
A reading in the red sector to the left (fig.1.g) indicates a fault in the charging system which will cause the battery to be under charged. A
reading in the red sector to the right (fig.1.i) indicates a fault which will cause the battery to be over charged.
note: Although not marked on the meter scale the 'oK' range for a 6 volt charging system is 6.8 to 7.5 volts.
3.7.
starter motor (12 volt)
note: this test requires that the battery is in good condition and is charged to at least 75% capacity.
3.7.1.
disable ignition system (remove fuse or similar) so that engine will not start.
3.7.2.
carry out a load test (para. 3.3.), if not already done, and note voltage reading.
3.7.3.
use the table on the meter (fig.1.J) to determine the equivalent minimum cranking voltage. note that for engines of less than 3.25 litres
take the next higher figure. for example:
a) 3.5 litre engine - load test result 11.0 volts, gives min. cranking voltage of 9.7 volts.
b) 1.5 litre engine - load test result 11.0 volts, gives min. cranking voltage of 10.2 volts
3.7.4.
operate the starter motor and note the voltage during cranking.
3.7.5.
A reading below the minimum cranking voltage indicates that the starter motor is taking excessive current. this may be due to poor
connections, to a faulty motor or to the battery being too small for vehicle.
3.7.6.
After test reinstate ignition system.
note:
for a 6 volt system test as above and note load test voltage. double this value and determine equivalent min. cranking voltage as in 3.7.3.
Halve the figure to give min. cranking voltage for the 6 volt system and then proceed from 3.7.4.
