"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
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."
