OVERVIEW
The battery is mounted in a protective box, located under the LH seat. It sits in a tray and is secured with clamp plates
and bolts.
The battery terminal posts allow for the battery cables to be connected with clamp type connections.
The battery positive terminal is fitted with a mega fuse, which is a 500 Amp device housed in a black fuse carrier,
integral to the battery clamp. Power feed to the BJB is taken from a tap on the battery clamp before the mega fuse.
In the event of a crash the mega fuse is designed to blow, this isolates the power from the generator and starter motor,
but allows power to be delivered, via the central junction box (CJB), to the rest of the vehicle.
The battery is a .
The battery is a H8, semi-sealed type. Each casing has a vent to allow for thermal expansion and to vent oxygen and
hydrogen gases, which are produced under certain charging conditions.
When removing the battery, ensure the alarm is disarmed and the ignition is switched off. Always disconnect the
negative terminal first and then the positive. When refitting the battery, always fit the positive terminal first followed by
the negative.
If the battery requires recharging, always use an approved constant current charger, designed for lead-calcium
batteries. DO NOT use a fast charger, as permanent damage to the battery may occur.
Starter Fuse
Incorporated in the cable between the battery and the starter motor/generator is a 500A mega fuse. The fuse is
mounted adjacent the battery positive terminal and is integral with the cable assembly. In the event of fuse failure, the
complete cable assembly must be replaced.
