Fuses and relays
There are 4 electric centres. The relays related to specific fuses are located in the
electric centres. Other relays are placed outside the electric centres.
The electric centres must always be kept clean. If a fuse blows, the fault must be
traced and repaired.
IMPORTANT: Fuses must not be replaced with new ones of higher rating as this
may damage the electrical equipment.
Power for extra equipment can also be taken from the spare fuses or unused
extra equipment fuses. A current source can be connected from the main current
pole of the starter motor through the new fuse. The current is then switched off
with the main switch.
