I have a Nordic Tugs 32, hull #215 which was built in 2002. The bow thruster is Seipner model SP 55 S. The boat was launched this past Monday, May 23. After the boat was floating and the engine (Cummins Diesel) started, I bump tested the bow thruster and it responded. After a short spin on the water, I returned to the marina and docked the boat, which requires use of the bow thruster. Initially, the thruster worked as expected. However, at the end of the docking maneuver the thruster began sounding and performing weakly, then nothing.
Since Monday, I have tried the thruster a few times and only get a click from the solenoid when I bump the joy stick. The battery was and remains fully charged. I have conducted a number of tests with the multi-meter. Continuity testing shows the 400 amp fuse to be intact. There is 12-13 volts DC at the: thruster, joystick (a.k.a control panel), and control box which is part of the thruster unit. Using a trouble shooting document from JPC-direct, I also did a jump test from the control wires at the control box to the negative terminal on the unit: only clicking. My current (no pun intended) theory is the solenoid is bad. However, I am not sure that fits with how the thruster gradually lost power when docking . Any thoughts or words of encouragement would be appreciated.

We have NT 32-238 with same bow thruster. I think that have identified the problem: the solenoid. I assume that you have confirmed that the battery terminals are corrosion-free and tight? To confirm that the solenoid is good or faulty apply your voltmeter to the bow thruster end of the solenoid have your partner activate the bow thruster while you measure the voltage across this terminal and the battery end of the solenoid and then from the bow thruster end to ground. There should be no drop across the solenoid and no drop to ground if the solenoid is good. In a pinch (battlefield repairs) you might try dismantling the solenoid and burnishing the contacts, but it is probably time to get a new one. Let me know how it turns out, please.

Had a similar issue, thruster would lose power and stop….
Mechanic sent out to shop, was an issue with the armature. Was rebuilt.
Has worked perfectly for over three years

Adding my $.02. We had a similar issue on 32-099 Hot Sauce. We thought it was the solenoid. Turns out, it was the thermo switch.

Thruster update:
After conducting a number of tests for voltage and continuity and not feeling confident about the conclusions, decided to try the bigger hammer approach.
A solid wack from Chris of tug Bruno (32-190) did the trick.
Hope your electrical issue is solved as easily.
