FSB 322-001, Charging System Voltage
(November 2013)
On vehicles equipped with a Volvo Engine built from January 1, 2010 to June 28, 2013 with
the left front battery box location (not the stacked battery box or Dometic system equipped
vehicles), the voltage drop on the charging circuit may be higher than is recommended when
utilizing the voltage drop test with the Intellicheck tester. The voltage drop is acceptable to
charge the batteries but the test using the Intellicheck tester may show failed or under
specification.

Checking
On some vehicles, the Intellicheck tester can erroneously indicate excessive voltage drop in
the charging system. If the Intellicheck tester indicates too high a voltage drop, perform these
steps to determine if corrective action is needed:

•
•

Clean and tighten all power connections on the alternator, batteries and cables.
Repeat the test with the Intellicheck tester and record the voltage drop reading for positive
and negative.

•

Add the two readings: If the total is 0.60 V or less then the voltage drop is acceptable
no further action is needed.
If the total is greater than 0.60 V then perform the following procedure:

W3083778

Sample calculation A + B = ≤ 0.60 V
Example: 0.19 + 0.29 = 0.48 (Passed) No further action required.
