1.1. Potentiometer
(speed dial)
In most cases this is likely to be caused by a faulty potentiometer.
Locate the potentiometer positioned behind the rear splash
guard. Remove guard and plastic seat unit, and disconnect and
remove the batteries. You should now be able to follow the wires
from the potentiometer to the controller (silver box – attached to
top of chassis). There is a small black push fit connector
connecting the potentiometer to the controller. Disconnect this
and re-fit the batteries. Your OSET will run without the
potentiometer but you will lose the ability to regulate the top
speed.
1. Order a potentiometer. There
are two types of these. A mk22
was fitted to models circa 2007-
2009. A mk47 was fitted to
models 2010-2012.
1.2. Connection
Check
There are many connections all over your OSET and as with
anything electrical it is important that there is nothing that could
compromise the system. Simply isolate each connection &
disconnect. Inspect each one and check for evidence of ‘arcing’,
debris, loose wiring or anything obvious. Waggling wires and
connections as you go you may be able to assign your problem to
a specific connector or portion of wiring.
1. Replacement connecting blocks
are available if you would like to
create a factory repair to your
OSET. Alternatively it is perfectly
ok to use a standard spade
connector, or if you are competent
solder the connection back
together, ensuring the wire has
been reinsulated.
1.3. Relay
The relay is located directly underneath the seat unit. It is a small
black box which is simply a switch, which operates when you turn
the key of your OSET. A relay which is operating correctly should
make a noticeable clicking noise when the bike is turned on.
Absence of the ‘click’ will probably mean that your relay is faulty.
A relay that is not working will also mean you will have none of
the charge indicating lights showing on the throttle body.
1. Replace the relay. Please ensure
you have the year of manufacture
and model of your OSET to hand
before calling as this does
influence which relay you will
need.
