7.1 Ground connection to handlebar
With an ohmmeter, the resistance between battery negative pole and the handlebar surface is
measured. If the resistance is higher than 3 ohms, a separate ground wire must be routed from the
negative battery terminal to one of the mo.switch housing ground points.
Handlebars that are not made of metal, e.g. Carbon, need a separate ground wire from the battery
negative terminal to each of the mo.switch housing ground points.
When tightening the M3 grub screw into the mo.switch housing, the tip of the screw penetrates the
handlebar surface and thus creates a secure ground connection between the handlebar and the
housing.
The further ground connection for the pushbuttons is then carried out with the grounding cables
supplied; connected at the mo.switch ground point with the M3 screw and the eyelet. In the pro-
cess the supplied chopper disc is placed between the eyelet and the housing.
The free ends of the grounding cables are connected to a terminal contact of each button. The
polarity does not matter.
All further ground connections, e.g. for the indicators and brake switch also carried out by using a
mo.switch housing ground point.
