>Hi guys, Has anyone ever had a problem with their dimmer switch? Can they
>short out internally?
Normally the contacts oxidize and get dirty over time if they are not
switched frequently. The oxidized contacts do not make a good contact
and the other beam does not come on because of an open circuit. Working
the switch will usually get it to work after a while. Once the contacts
become corroded they can be problematic.
The switch is not likely to be your shorting out point. Check for
debris build up around the external foot switch connections and at the
headlamp subharness.
The bulbs are the resistive load. If there is an internal short that
cuts down the filament resistance you could draw more current than you
generator could produce.
