Fiat 55 Automobile User Manual


 
1 General description
The electrical system is of 12 volt negative
earth type and employs a belt-driven
alternator and a pre-engaged type starter
motor.
The models in the range are all adequately
equipped with electrical accessories, while SX
versions also have power windows and
centralised door locking plus a check control
system (Section 34).
2 Battery - inspection, charging,
removal and refitting
2
1 The battery is of maintenance-free type and
under normal circumstances, no topping up
will be required, but regularly check that the
electrolyte level is between the minimum and
maximum lines on the translucent battery
casing.
2 If the electrolyte level does drop below the
minimum line, suspect a leak in the battery
casing or that the alternator is overcharging. If
the latter is the case, rectify the alternator fault
and then prise out the two rectangular plugs
from the top of the battery and top up with
distilled or purified water.
3 Always keep the battery terminals clean
and smear them with petroleum jelly to
prevent corrosion.
4 The battery will normally be kept fully
charged by the alternator, but it is possible for
the battery to become discharged if the daily
mileage is very low with much use being
made of the starter and electrical accessories.
5 When the battery begins to deteriorate with
age it may also require a boost from a mains
charger.
6 Disconnect both battery leads before
connecting the mains charger.
7 To remove the battery from the car, first
disconnect the leads from the battery
terminals (earth first) and then unscrew the
securing clamp from the casing projection at
the base of the casing (photo).
8 Lift the battery from its mounting platform.
Refitting is a reversal of removal. Reconnect
the earth cable last.

If battery terminal corrosion
has occurred, it may be
neutralised by applying
sodium bicarbonate or
household ammonia.
