Before seeking assistance at the help desk of your Sidepower 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 understand how the system is intended to work.
If you are unable to understand what to check, you must consult a professional.
Trouble shooting
Solution
Re-fasten or replace the propeller and/or key.
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 bat-
teries 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 cor-
rectly. In a 24V boat the thruster will operate down to approx. 12V, but the perfor-
mance 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 connec-
tions, battery size and condition, fuse and main power switch performance
If less than 10,5 V / 21V the thruster will not perform at specified effect.
If there are growth in the tunnel, this will disturb / block the waterflow and
especially barnacles on the propeller will greatly reduce performance.
Re-charge battery(ies), if this is not sufficient, replace battery(ies).
Check for bad cable connections, if necessary tighten/re-adjust connections.
Check cable size in accordance to manual.
Check
Are the propellers in the tunnel fastened correctly
on the prop-shaft (key present)
Check that the voltage of the electromotor are cor-
rect 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 try-
ing to run it. Keep main engine(s) running to have
continous charge to the batteries.
Check voltage at thruster when running
Check that the propeller, gearhouse and tunnel is
free from growth / barnacles etc.
Solenoid flapping, most probable cause: low
voltage.
»
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.
