Battery condition is determined by measuring battery terminal voltage after a specific discharge current is applied for a specified time period.

Possible Sources

  • Battery
  • Wiring, terminals or connectors

Visual Inspection and Pre-checks

  • Inspect wiring, terminals and connectors.
  • Inspect the battery.
  • Inspect the battery mounting.
  • Inspect high current BJB connections.
A1 TEST THE BATTERY CONDITION

NOTE: Failure to fully charge the battery before retesting may cause false readings.

  • Using the Diagnostic Battery Charger and the battery cables removed from the battery, verify the battery condition.

Is the battery OK?
Yes RETURN the battery to service.
No If the analyzer reads REPLACE BATTERY or REPLACE-BAD CELL, INSTALL a new battery.
REFER to: Battery (414-01 Battery, Mounting and Cables, Removal and Installation).
Run the BMS reset app in the diagnostic tool after replacing the battery.
