Battery Isolator
A heavy-duty battery isolator is mounted on the side of the main box. This must be turned on
before anything on the machine will work. It is primarily intended as a means of quickly
disconnecting the battery in case of an emergency, or before doing maintenance.

Battery Charger
Testing
If the battery does not hold its charge, or will not accept a charge, the fault may be either with the
battery or the charger. Follow the steps below to determine whether the charger is working
correctly:
I.
Remove the access panel on the main box.
II.
With a multi-meter in DC voltage mode, measure the voltage of the battery when the
charger is not plugged in. It should normally be between 12.2 & 12.6 volts.
III.
Plug the charger in, and check the voltage again. It should quickly rise to around 13 volts,
then slowly increase to about 13.7 volts.
IV.
If the voltage doesn’t rise, check the wall socket, the charging lead, and the 2
-way plug
from the charger that connects into the loom.
V.
If the tests indicate a faulty charger, replace it as detailed above.
Removal and Refitting
I.
Loosen the screws holding the outer cover panel and lift it off.
II.
Disconnect the plug connecting the charger to the wiring loom.
III.
Bend the retaining tab down with pliers or an adjustable spanner, and slide the charger
out.
IV.
To replace, slide a new charger in, and bend the tab back up to retain it.
V.
Connect the wiring plug and socket.
