Battery Test (Parasitic Load)
NOTE:
Keep the battery disconnected for this test.
This test is for excessive parasitic drain on the battery.
Keep the ignition OFF.
IMPORTANT:
Do not start the vehicle during this test; the F-1860 may be damaged as a
result.
♦
Set the F-1860’s rotary switch to the 20A position.
♦
Insert the black lead into the
COM
socket and the red cable in the F-1860’s
20 A terminal.
♦
Disconnect the positive (+) cable from the battery.
♦
Connect the positive (+) test lead of the F-1860 to the positive (+) battery
terminal.
♦
Connect the negative (-) test lead of the F-1860 to the negative (-) battery
terminal.
♦
Press the MAX/MIN button on the F-1860.
Parasitic readings should not exceed 100 mA.
If parasitic readings are in excess of this value, remove the circuit fuses one by
one, until the fault is located. Also check all non-fused applications such as
headlights, relays and capacitors in the instrument panel.
Reconnect the battery cable for the next test.
(4) Battery Test (Load)
This tests the battery’s capacity to deliver sufficient cranking voltage.
♦
Set the F-1860’s rotary switch to the voltage position (V).
♦
Connect the positive (+) test lead to the positive (+) battery terminal.
♦
Connect the negative (-) test lead to the negative (-) battery terminal.
♦
Press the MAX/MIN button on the F-1860.
