Electrical system, description
Regarding: L60F, L70F, L90F
The machine has a 24 V electrical system with two 12 volt bat‐
teries connected in series, located on each side of the rear frame
in the counterweight.
The battery disconnector is located under the radiator casing.
Fuse FU74 is next to the battery disconnector and supplies volt‐
age to certain components (e.g., voltage converter for radio),
even when the battery disconnector is turned off.
Voltage feed takes place via a fuse box located in the engine
compartment. The fuse box contains main fuse as well as fuses
for preheating coil and secondary steering pump.
Relays and fuses are mainly located in the electrical distribution
box behind the operator's seat and are accessed by removing the
cover for the electrical distribution box. The cover's inside is pro‐
vided with a decal that informs which power-consuming compo‐
nent is connected to each relay and fuse. There is a built-in
terminal for fuse test in the electrical distribution box. The relays
in the electrical distribution box are interchangeable.
Components are marked according to which function group they
belong. The first two digits indicate function group and the other
digits are running numbers, e.g., SE2203.
NOTE! For working on the electrical system, follow the instruc‐
tions in section
