Starting Circuit Test (cont'd)
Test 3b
If the reading between terminal D and earth is below 8.0V,
connect the voltmeter between terminal E and earth. An
increase in the reading to 8.0V indicates either a faulty start
relay or a fault in the feed from the transmission selector
switch to the relay solenoid. Check also the solenoid earth
connection.
If the reading between E and earth is less than 8.0V, the fault
must be in either the starter switch or in the wiring between
the solenoid, starter switch, and the start relay.
Test 4
Connect the voltmeter between battery negative and starter
earth connection B. The reading in the 'start' position should
be practically zero, maximum permissible reading 0.25V.
If the reading is above 0.25V, a high resistance in the earth
lead or connections is indicated.
Test 5
Connect the voltmeter between battery positive and the
starter main terminal A. With the starter switch 'off', the
voltmeter should indicate battery voltage, but it should fall to
practically zero when the switch is turned to the 'on'
position, maximum permissible reading 0.25V.
Test 5a
If the reading is above 0.25V, a high resistance is present in
the insulated lead or in the solenoid. Connect the voltmeter
between the battery positive and solenoid connection H. If
the voltmeter now reads zero with the switch closed, the
fault is in the solenoid.
Finally refit the engine stop fuse.
