- Battery
If the voltage is lower than 12.30 V it is only half charged, if it reaches 12.48 V it is three-quarters charged and at 12.66 V it is fully charged.
CAUTION
- - Do not connect or disconnect the battery to or from the electrical system of the ve-hicle when the engine is running.
- - Do not invert the terminal connections (even for a few moments) as this would damage the alternator rectifier.
- - When connecting the battery charger to the battery, first establish the connections and then start the charger.
- - If it becomes necessary to start the en-gine with temporary cables and with an auxiliary battery, the voltage of the external battery must not exceed 12 V.
- - Before charging the battery it is necess-ary to remove the clamp from the negative terminal.
- - When recharging check that the tempera-ture of the electrolyte does not exceed 45°C.
CAUTION
- - Do not touch the negative and positive termanals at the same time.
- - Keep all naked flames away from the vehicle during recharging of the battery.
When replacing the battery follow the directions for use. If the charge of the replacement battery is potentially higher than the old one the higher voltage could cause the fusion of the starter motor induction coil or damage the pinion or crown.
CAUTION
- If the electrolyte level in one of the cells of the battery should fall below the mimimum level notch on the side of the plastic con-tainer, carefully open the cap cover and add de-ionized distilled water as with ordi-nary batteries.
NOTE: Do not recharge the battery at a voltage of above 15.5 V with a strong flow of current. Use instead a normal 12 V battery charger connecting the positive cable (red) to the (+) terminal of the battery and the negative cable (black) to the (-) terminal of the bat-tery.
In case the battery of the vehicle is con-nected temporarily to an external battery connect the positive terminal to the posi-tive terminal and the negative terminal to the negative.
