CONDITIONS
DETAILS/RESULTS/ACTIONS
C1: CIRCUIT CHECKS
• NOTE: Freelander 2 = Charge warning lamp is driven by the central junction box (from the powertrain control module) to
the instrument panel cluster via the CAN bus
• NOTE: Defender = Charge warning lamp is driven by the powertrain control module to the instrument panel cluster via
the CAN bus
Freelander 2 = Refer to the electrical circuit diagrams and check the (LIN) circuit between the
generator and the engine control module for short circuit to ground, short circuit to power, open
circuit, high resistance faults
Defender = Refer to the electrical circuit diagrams and check the (D+ and ALTMON) circuits between
the generator and the engine control module for short circuit to ground, short circuit to power, open
circuit, high resistance faults
Are any circuit faults evident?
Yes
Repair the circuit as required GO to Pinpoint Test
B.
No
GO to Pinpoint Test
D.

CONDITIONS
DETAILS/RESULTS/ACTIONS
D1: CIRCUIT CHECKS 1
• NOTE: Freelander 2 = The heated rear screen is timed to operate for 12 minutes
• NOTE: Defender = The heated rear screen is timed to operate for 8 minutes
Connect a voltmeter to the vehicle battery
Switch ignition state to on (engine off)
Turn off all electrical loads e.g. (blower, radio, interior lights etc.)
Start the engine, switch on the heated rear screen
Ensure the heated rear screen is on (see note above) and that the air conditioning system is off.
Voltage measurement
Measure the voltage drop between the generator body and battery negative terminal and record
the value (V2)
Does the voltage drop value (V2) = less than 0.3 Volts ?
Yes
GO to D2
.
No
Switch off engine. Circuit check. Refer to the electrical circuit diagrams, check the generator body
and battery negative cables for loose or corroded connections. Repair any circuit faults, retest the
generator GO to Pinpoint Test
B.
D2: CIRCUIT CHECKS 2
Voltage measurements
Measure the voltage drop between the generator B+ terminal and battery positive terminal and
record value (V3)
Does the voltage drop value (V3) = less than 0.3 Volts ?
Yes
Install a new generator. Refer to the warranty policy and procedures manual, or determine if any
prior approval programme is in operation, prior to the installation of a new module/component
No
Switch off engine. Circuit check. Refer to the electrical circuit diagrams check the generator B+
terminal and positive battery cables for loose or corroded connections. Repair any circuit faults,
retest the generator GO to Pinpoint Test

OVERVIEW
The battery is located behind a cover on the Left Hand (LH) side of the engine compartment. The battery sits in a tray and
is secured in position with a clamp plate and bolt assembly. The battery supplies electrical power to the starter motor,
generator and BJB.
The BJB is mounted adjacent the LH front suspension turret. The BJB contains fusible links, blade and J-case fuses, and
relays to distribute electrical power to various vehicle systems and junction boxes.
