purposes, there are small flags on the cable. If these small flags
are not present, hold the cable to the battery briefly in order to
determine the correct polarity prior to the actual connection.
Connect the plus and minus cables of the turn signal with the
supply lines of the original turn signals, e.g. underneath the
fitting with small soldering points, which are insulated with
heat shrink tubing (slide on the heat shrink tubing, then solder
the cable, pull the heat shrink tubing over the soldered joint
and shrink it with a lighter, heat gun or similar). Ensure that
the cables are connected correctly and in a short-circuit-proof
manner, do not confuse plus and minus or the left and right turn
signal side, under no circumstances should you use terminal
blocks for the connection.
Following successful connection, be sure to check that the
electrical system is functioning correctly before setting off.
The flashing frequency (speed) is set at 90 +/- 30 cycles per
minute. This means that the turn signals must flash between 60
and 120 times each minute.
If turn signals are installed which have a lower total wattage
than the originals, this normally results in a flashing frequency
which is too high or the turn signal stopping completely. The
correct flashing frequency must then be restored using an
appropriate flasher or with the aid of resistors (which simulate
the missing wattage).
Various universal flashers, vehicle-specific flashers and resistors
in different sizes are available as accessories.
The use of resistors is particularly recommended where the
vehicle has a combined relay unit which cannot be replaced
(it usually has more than three cable connections available
in that case) or when the turn signals are controlled by the
motorcycle's processor. The resistors are installed in the right
and left turn signal circuits respectively in parallel connection.
They can be positioned directly before the turn signals or
in another position within the right or left turn signal circuit
(whether this is at the front or the rear).
The required resistance can be determined according to the
following formula:
Required resistance R (in ohms) is equal to the sqaure of the
