Engine Electrical System; Check The Electrolyte Level; Changing Fuses - Nanni V6.180 Instruction Manual

Engine electrical system

I Attention! : Stop the engine and the cut the battery
supply before working on the electrical circuit.
Alternator belt
Make this check after running the engine when the belt is
slightly hot.
I Attention! : Some parts of the engine can be extremely
hot.
To replace the belt, act on the tensioner A until the holes B
are aligned then use a locking pin to lock it. You can then
take off and replace the belt.
After replacing it, move the tensioner A to release the
locking pin and remove it in order to tighten the belt. Then
release the tension on the automatic tensioner A which will
then apply the correct tension on the belt.

Check the electrolyte level.

The starter battery must remain clean and dry. Oxida-
tion or the deposit of impurities on the battery and on its
terminals may lead to short circuits, voltage drops and
premature discharging, notably in wet weather.
The battery terminals and the cables must be cleaned
with a brass brush in order to remove any oxidation.
Tighten the cable terminals and lubricate them with ap-
propriate grease.
If the battery is replaced, use a battery with similar specifi -
cations to the previous one.
If starting with an emergency battery and connection ca-
bles, proceed as follows:
- Connect the emergency battery to the main battery
by connecting the + to the + and the – to the -. When the
engine has started, remove the connection cables.
You should disconnect the 2 battery cables when:
- You use a battery charger
- Before carrying out any work on the electrical equip-
ment
- Before carrying out any welding work

Changing fuses

The protective fuses in the electrical system are disposable.
These blown in the event of a voltage surge or a short-
circuit in order to prevent any damage to the parts. In the
event some anomaly has caused a fuse to blown, fi nd the
cause before changing the fuse. Always use a fuse with the
properties as the one being replaced
