Checking alternator absorption and recharging function
Checking alternator absorption and recharging function
Remove the engine compartment cosmetic shields (
Remove the left hand lateral cosmetic shield.
E3.13).
Remove the battery connection cover.
Disconnect the alternator positive cable (1) from
the battery and connect a suitably calibrated
digital multimeter such as (Beckman T11 OB)
between the cable and the battery.
To measure the voltage and maximum current
generated by the alternator, preferably use a
digital multimeter and a HALL effect
amperometric clamp meter.
Fit the amperometric clamp meter on the cable
connected to the alternator.
Start the engine and run at 3,000 - 4,000 rpm.
Switch on all available current devices one by
one and measure the generated current on
the multimeter. Replace the alternator if the
current read is more than 5A less than the
prescribed value.
