Charging System (Lf, L3): Diagnosis Mazda 3 BL

BATTERY INSPECTION [LF, L3]

WARNINGSince battery acid is toxic, be careful when handling the battery. Since battery acid is highly corrosive, be careful not to allow it to contact clothing or the vehicle. In case battery acid contacts skin, eyes, or clothing, flush it immediately with running water. Especially if the acid gets in the eyes, flush with water for more than 15 min and get prompt medical attention.

Electrolyte gravity

  1. Measure the electrolyte specific gravity using a hydrometer. If it is less than the specification, recharge the battery. (See «BATTERY RECHARGING [LF, L3]»(ref-345206-S01761960272009102000000) ). Standard electrolyte gravity 1.22-1.29 [20°C {68°F}]

GENERATOR INSPECTION [LF, L3]

CAUTIONDo not apply direct battery positive voltage to generator terminal D, otherwise it could cause damage to the internal parts (power transistor) of the generator.
