Yellow is directly connected to battery +ve. White
and black may also be battery +ve (depending on the
control switches). Green is battery -ve and blue and
red are the control pot.

Battery wiring
Use only good quality battery connectors: the
controller feeds current back the battery during
braking and if a battery connector falls off when
braking this regenerated current can pump up the
voltage on the dud battery connection. Although the
controller is protected against damage, this is not
advised since control is lost. The same will happen if
a fuse or circuit breaker opens during braking.

Wire size.
Use heavy duty wire for the battery leads and make
them as short as possible. This also applies to the
battery linking wire on 24v systems.
4mm (12awg) wire is 'officially' rated to handle 41
amps continuously. At 100 amps it gets too hot to
touch within about 60 seconds. We therefore suggest
you use at least 6.0mm² (10awg) wire for battery
connections.
On the 12v controllers, voltage loss in the wire is
important and you may need to use two lengths of
6mm² wire for the battery - depending on their
length. Excessive voltage loss will cause the voltage
