Operation

The BSM will change color dependent on its input voltage; the color will indicate the operational state of the battery. The following table shows the approximate voltages for each color, in practice the color changes gradually between RED and GREEN as the battery goes from discharging to charging:

Conventional System

Color	12V Version	Meaning
Slow Flash RED	Less than 10.75V	Extreme under voltage - recharge battery now!
RED	Less than 12V	Battery low or under load (engine off).
	13.8V to 12.0V	Expect Orange / Yellow for a fully charged battery (engine off).
GREEN	More than 13.8V	Battery on charge.
Fast Flash RED	More than 15.25V	Over charging or charge system high voltage, check regulator!

Fitting

Bezel Version: Drill a 14.0mm hole (tight ⁹/₁₆"). Place the bezel through the hole from the front. From behind the panel push the BSMs LED through the bezel until it clicks. If the panel material is thin it may be necessary to use silicone sealant to secure the bezel at the rear.

Connections

Join the positive (RED) and negative (BLACK) wires to the ignition circuit and earth, according to the system's polarity. On the handlebar version one core of the 'figure-of-eight' cable has a feint ridge running along the outside, this is the positive lead. For positive earth systems RED (ridged) will be to earth and BLACK to ignition. If the BSM fails to light up the connections could be reversed; the unit will not be damaged, try again! Be aware that voltage drops from heavy loads (headlamp) may effect (lower) the BSM results.
