Before seeking assistance at the help desk of your Side-Power dealer/distributor please perform these tests and make notes of all
measurements to ensure that they have as much information as possible to work on.
NB! All check points and solutions must be carried out after consulting the relevant information elsewhere in this manual to un-
der-stand how the system is intended to work. If you are unable to understand what to check, you must consult a professional.

Solution
Check the fl exible coupling/shear pin and the motor installation to ensure correct con-
nection of the fl exible coupling before re-fi tting the electromotor.
Re-fasten or replace the propeller and/or key/drive pin.
In case of a failure inside the gearhouse, we advice to get a replacement gear-house
instead of attempting to repear the internal gear and bearing system.
If wrong, contact your dealer or distributor to obtain parts with the correct voltage.
The no load voltage should be:
12V system =12,7V / 24V system = 25,4 V. If below 12,3V / 24,6V your batteries are
not in a good charge state or worn out and must be recharged or replaced before trying
to run the thruster.
If less than 8,5V at the thruster the voltage is to low for the thruster to operate correctly.
In a 24V boat the thruster will operate down to approx. 12V, but the performance will
be very bad. Find and correct the reason for this low voltage which will probably be
one or more of these points: main battery cable sizes and connections, battery size and
condition, fuse and main power switch performance.
If the thruster runs in both directions, try the same in the connector that goes into the
back of the control panel. If it also works in this position, check the contact and wires
on the back of the panel and try to engage this again by pushing both ON buttons
simultaneously. If the panel does not turn on (see control light), measure the voltage
between the Red and the Black in the contact going into the thruster. If the voltage is
good, chances are that the panel is not working.
If it works by the thruster, and not by the panel there is a bad contact or a broken lead
the control cables between these two test points.
Measure that you have the correct voltage between the Red (+) and all the other col-
ours in the contact. If you do not get a reading.
Between main minus (A1 on motor) and the blue and the grey wire connected to the
sides of the main solenoids you should have the same voltage as between
the main battery cables on the thruster. If not, check that the internal wiring on the so-
lenoid is ok and measure that there is contact through the magnetising spools of each
side of the solenoid (measure between the red and blue on one side, and red and grey
on the other side with an Ohm meter.). If there is no
contact between these, the solenoid is broken and needs replacing.
If less than 10,5 V / 21V the thruster will not perform at specifi ed eff ect.
If one or more brushes are loose/has no tension from the brush-spring, the performan-
ce will be low.
If there is growth in the tunnel, this will disturb/block the waterfl ow and especially bar-
nacles on the propeller will greatly reduce performance.
Re-charge battery(ies), if this is not suffi cient, replace battery(ies).
Check for bad cable connections, if necessary tighten/re-adjust connections.
Check cable size in accordance to manual.
Shut off thruster main switch, tap slightly on the solenoid to see if it will release. Turn
on thruster main switch. If solenoid is still in lock-in mode, replace solenoid.
Check
If the fl exible coupling between the motor and driveshaft is
not fi tted correct inside the boat.
Are the propellers in the tunnel fastened correctly on the
prop-shaft (key/drive pin present)
With the motor removed, turn the driveshaft from inside
the boat to feel if the gears are engaging and turning the
prop-shaft.
Check that the voltage of the electromotor is correct for
your installation by their labels.
Check the voltage at the thruster between main minus input
(A1 on motor) and main plus input point:
Check the voltage at the thruster while you are trying to
run it. Keep main engine(s) running to have continous
charge to the batteries.
If the main solenoids on the thruster are not even trying to
engage (clicking) they are probably not getting a "run" sig-
nal from the control system. Try to run the thruster without
the panel by directly connecting the red and the blue or the
red and the grey wires in the controlcable contact coming
from the thruster.
If the thruster does not run at all, or only in one direction in
the above tests, check the internal wiring on the thruster
motor, solenoids and electronic motor inter-face box to be
in accordance with the wiring diagram and ensure that all
connections are clean and tight.
Check voltage at thruster when running.
Check that all the brush-springs sits correctly on the brus-
hes in the electromotor.
Check that the propeller, gearhouse and tunnel is free
from growth/barnacles etc.
Solenoid fl apping, most probable cause:
low voltage.
Solenoid lock-in, auto stop of thruster, auto retry every 10
seconds.
»
The electromotor runs, but there is no thrust.
»
The thruster does not start at all or works only in one direction.
»
The thruster has an unexpected low performance.
»
The thruster runs for approximately 0,5 seconds every 4 seconds.
»
The thruster runs for approximately 0,5 seconds every 10 seconds.
