General Information, Specifications and Maintenance
There is one circuit breaker (1) located under the right
side of the dash that protects the keyless ignition circuit.
It is mounted to the side of the steering column mount just
below the flasher.
This circuit breaker will trip if there is a short or grounded
wire in the applicable circuit. The circuit breaker will auto-
matically reset once it cools. If the circuit breaker contin-
ually trips, check the system for shorts, grounds or
defective electrical components.
Under normal operating conditions the circuit breaker
should never need replacement. however, if a circuit
breaker does not automatically reset, the breaker is de-
fective and replacement is required.
IMPORTANT: The circuit breaker has a long terminal (2)
and a short terminal (3). The short terminal is labeled
"BAT" and the long terminal is labeled "AUX". Connect
the wires from the battery to the "BAT" terminal and con-
nect the other wires to the "AUX" terminal. If the wires
are connected to the wrong terminals and the circuit
breaker trips because of a short or grounded wire in the
circuit, the contacts in the circuit breaker will melt
together and the circuit breaker will not protect the circuit
because it cannot open.
d. Fuse and Relay (Fuel Shut Off Solenoid)
There is one fuse (4) located under the engine cover.
Open the engine cover to gain access to this fuse.
The fuse is a 5 amp fuse which protects the fuel shut off
solenoid, located in the engine harness (5). To gain
access to the fuse, remove the protective cover (6) from
the fuse holder (7).

There are two fuses (8) located on the bottom side of the
equalizer (9). These two fuses are 125 amp fuses and are
located on the 12V and 24V positive terminals of the
equalizer. These fuses protect the 12V and 24V circuits
of the equalizer. You will require a small telescoping mir-
ror to check these two fuses.
If a 125 amp fuse blows, the fuse along with the mounting
hardware will have to be replaced as a kit.
Replace a 125 amp fuse as follows:
1
1. Remove the blown fuse and associated hardware.
Discard all items.
2
2. Insert the new capscrew (10) through the tab (11) on
the equalizer (9).
3
3. Place a flat washer (12) and new fuse (8) onto the
capscrew. Position fuse as required to best see
through the clear window.
4. Place the positive cable (13) onto the capscrew.
5. Place the nylon shoulder washer (14) onto the
OM1560
capscrew and place against the positive cable with
the hub toward the cable.
6. Secure in place with a flat washer (15),
lockwasher (16) and hex nut (17). Torque the hex nut
to a maximum of 100 lbs/in (11 Nm).
