ELECTRICAL
GENERAL INFORMATION
TESTING IN POSITION
Detailed information of electrical systems, component
locations and circuit diagrams are covered in the
Defender Electrical Troubleshooting Manual.
Charging circuit resistance test.
1.  Connect a low range voltmeter between
generator terminal marked B+ and positive
terminal of battery.
This section covers checks of the charging system.
GENERATOR TESTING
Service repair no - 86.10.01
Charging system check
1.
2.
Check battery is in good condition, with an open
circuit voltage of at least 12.6 V. Recharge or
substitute battery to carry out test.
Check drive belt condition See SECTION 10,
Maintenance,  Under bonnet maintenance.
Check battery connections are clean and tight.
Check generator connections are clean and
tight.
3.
4.
5.
Ensure there is no drain on battery from, for
example, interior or exteriorlamps.
2.
3.
Switch on headlamps, start engine. Run engine
at approximately 3000 rev/min. Note voltmeter
reading.
Transfer voltmeter connections to frame of
generator and negative terminal of battery, and
again note voltmeter reading.
Generator test
Following instructions refer to use of suitable test
equipment using a carbon pile rheostat.
6.
7.
8.
Connect test equipment referring to
manufacturer’s instructions.
Start engine and run at 3000 rev/min without
accessory load.
Rotate carbon pile load control to achieve
greatest output (amps) without allowing voltage
to fall below 12.0 V. A reading in amps, of
generator output should be obtained.
Run engine at 3000 rev/min, switch selector to
regulator test, read voltmeter. A reading of 13.6
to 14.4 V should be obtained.
9.
10.
Switch selector to diode/stator test, switch on
headlamps to load generator. Raise engine
speed to 3000 rev/min, read voltmeter, needle
must be within ’OK’ range.
4.
If reading exceeds 0.5 volt on positive side or
0.25
volt on negative side, there is a high
resistance in charging circuit which must be
traced and remedied.
