In the electric plan there are different fuses and fuse holders that have the following functions:
There are 12 fuses located in the fuse holder pos.17 and they have the following functions and features
POSITION 1 : 30 A fuse vacuum motor (STANDARD)
POSITION 2 : 5 A fuse control board and battery charger protection;
POSITION 3 : 30 A service supply protection fuse (transformers, function control board, etc);
POSITION 4 : 10 A fuse pump protection;
POSITION 5 : 3 A fuse flashing light protection;
POSITION 6 : 10 A fuse for the protection of the 24V transformer 1 output (drive motor temperature indicator
warning light, drive motor temperature alarm buzzer, reverse buzzer, drive system operation warning
light, flashing lights)
POSITION 7 : 5A reverse light protection fuse;
POSITION 8 : 10 A fuse for the protection of the 24V transformer 2 output (all lights, horn, headlight warning
lights, handbrake warning light, handbrake buzzer)
POSITION 9 : 30 A suction motor protection fuse;
POSITION 10 : 3 A lid actuator protection fuse;
POSITION 11 : 3 A drive motor cooling fan protection fuse;
POSITION 12 : 3 A battery-charger cooling fan protection fuse;
Fuse pos.24: 80 Ah fuse BRUSH MOTORS PROTECTION
ATTENTION:This fuse is used by the function card to control the correct absorption of brush motors
(amperometric protection). It is possible that, although the motor reducers work with a correct absorption, error E1
appears on the display.
In this case there is an oxidation of the fuse that gives a wrong reading.
Please proceed as follows:
- Unscrew the 2 nuts pos.25 that fix the fuse of 80 Ah pos. 24
- Clean the fuse holder and oil it with vaseline
- Reassemble the nuts.
IMPORTANT: use exclusively the spare fuse by Eureka
Fuse pos.27: 125 A fuse PROTECTION OF THE DRIVE SYSTEM
TO REPLACE IT PROCEED AS FOLLOWS:
Remove the 2 nuts pos.26;
Replace 125 A fuse pos.27 with a fuse of equal amperage and with the same manufacturing characteristics;
Reassemble the 2 nuts.
Fuse pos.21: 20 A fuse CONTROL BOARD CARD PROTECTION;
TO CHECK OR REPLACE IT, PROCEES AS FOLLOWS:
Use a 2.5mm Allen wrench and remove the 10 clamping screws (see position 23) from the instrument panel, including
the respective nylon washers;
Carefully turn the instrument panel (see position 22), follow the arrows and make sure not to jerk it as it may damage
the electrical system;
Remove the 20 A fuse (see position 21), check it and replace it if necessary with a fuse of equal amperage;
Put the instrument panel back into place (see position 22);
Put the washer and screws back into place (see position 23) and close the panel using the special wrench, make sure to
