 Confirm battery contacts on both sides (Bat. and
Robomower) are not loose/damaged
 Check battery fuse (30A) is not blown (located in
battery case)
 Check main fuse (1A) and charging fuse (5A) are not
loose/blown/rusty (located on connector board (in
manual controller pocket under black/gray cover)
 Confirm good contact between m. controller cable

 Open the power pack cover and check connections
The Power Pack must have at least 14 volts
for the Robomower to wake up. Connecting
a standard 12 volt, 1-3 amp automotive type
charger to the connectors on the outside of
the power pack and charging for 12 hours
will usually bring the voltage up to 14 volts,
enough to wake up the mower. If so, allow
the mower to fully charge the power pack
on-board as normal. If it does not succeed,
replace the power pack.
(The positive+ connector on the power pack
is the connector closest to the 30-amp fuse).
