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

GO to Pinpoint Test

TEST

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

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

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

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.
