"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."
