REMOVAL, INSTALLATION AND WIRING
OF ELECTRICAL COMPONENTS
This section will show and explain the correct wiring
of switches and relays, and when and where battery
voltage should be with the key switch (ignition) "ON"
or "OFF" for the electrical components.
This section will also explain the removal and
installation of the switches, relays, EIC board, and
main wire harness.
Before servicing, changing or adding any electrical
components, read the following precautionary
statements.
IMPORTANT: Do not connect any power or ground
electrical circuits at the ignition key switch, the cab
electrical fuse panel, or the cab ground terminal in
the fuse panel area unless there are written
instructions from New Holland telling you to do so or
damage and false readings with the EIC board may
occur.
SECTION 55 - ELECTRICAL SYSTEM
IMPORTANT: If any servicing or adjustments require
the battery to be disconnected, or welding is required
on the skid-steer loader, disconnect the negative (–)
ground cable. Failure to disconnect the battery may
result in damage to the EIC (Electronic Instrument
Cluster) monitoring system and other electrical
components.
IMPORTANT: If the EIC requires removal from the
dash area of the skid-steer loader, disconnect the
negative (–) ground battery cable. This will shut off
power to the EIC and prevent damage to the EIC
board or blowing the 5-amp fuses if the board is
accidentally grounded.
IMPORTANT: Do not service the EIC board with
magnetized tools (wrenches, screwdriver, etc.) or
magnets. Severe damage to the EIC board may
occur.
