Speed Sensor - APRILIA RS4 125 Service Station Manual

RS4 125
h - Disconnect the clamps from the battery and
check the voltage, if voltages are detected of less
than 12.8 V, proceed with a new recharge of the
battery starting from point c of the recharge pro-
cedure of the new battery, otherwise go to point i
i - The battery is now completely activated, disconnect the battery charger from the fuel supply grid,
disconnect the clamps from the battery and proceed to fitting the battery on the vehicle.
BATTERY
(12 V - B9 - B)
In case of malfunction check first that the recharge
system works properly. To check the battery, re-
move it from the vehicle, and proceed as follows;
visually check that:
- there are no signs of sulphation (signalled by
white colouring of one or more cells);
- the electrolyte level is between the two "MIN" and
"MAX" reference notches;
- the container (outer casing) does not leak.
Charge the battery slowly for at least 10 hours.
With a densimeter check the electrolyte density at
every cell after recharging. If the density is below
1.26 at any cell or if the off-load voltage is lower
than 12V, the battery surely needs to be replaced.
