Issue: A customer may report a concern with a flat battery
or poor starting; when testing the battery it is determined
that a charge is required.
Cause: When charging a battery (both primary and
secondary) with a BMS (battery monitoring system) fitted,
the earth from the charger must be connected to a
suitable chassis or engine earth (check Topix for
appropriate location). This allows the BMS to see the
current going into the battery. However when using a
diagnostic charger from Midtronics such as GR1, GRX or
GR8(110 volts) this connection process can cause an
incorrect battery analysis due to the extra resistance in
the wiring when connected to a chassis or engine earth.
Action: When using a Midtronics GR1, GRX or GR8 you
Content are required to remove both battery leads from the vehicle
to carry out correct analysis and charge to the battery. DO
NOT connect the diagnostic charger to any other circuit or
chassis point other than the battery negative terminal as
advised in the Battery Care Requirements.
Battery replacement if stated on Diagnostic charger: If
it is determined that a battery requires replacement,
always refer to the appropriate section of the workshop
manual for instructions on removing and installing the
battery from the vehicle. Vehicles fitted with a Battery
Monitoring System (BMS), the BMS module must be reset
following the installation of a new battery. The BMS
module reset procedure must be performed using an
approved diagnostic system.
Care points: Reset customer settings as appropriate after
battery disconnection from the vehicle.
