   Hi. Just bought a Hanse 400 from 2007. On test sailing 2 weeks ago everything worked, but now winch and bowthruster are not working and there is no voltage on the two brakers in the control panel for anchor winch and bowthruster (number 2 and 3 switch from top in right switch row.
Would like to check the fuses for theese, but cant find them. Anyone know where to look?

	There are no "fuses" for those switches as they are all resettable thermal breakers. Those two are just 5 amp (anchor winch) and 15 amp(bow thruster). Use the switches to reset themselves. The power to the switches comes from relay K1, which has an interlock to only operate when the main engine is running the interlock uses 2 amp fuse between alternator and the main control panel.. They both control their own solenoid relays located in lower compartment Main power for the Anchor and bow thruster is protected by the square black thermal breakers in the lower electrical space. I think they are labelled. Is there is no light on the switches when switched on then there is an issue with K1 relay and the engine running interlock. Cheers Edited by DJgun - 16 May 2024 at 13:34

	Make sure your engine is running. These systems will not work otherwise.

	Yes, engine must be running, but still no power on controls in panel.

	Hi Frodi There is a fuse in the wire from the alternator to the control panel. That wire is what allows K1 relay to switch on. From memory the fuse is on the port side of the engine. If that is blown then those switches will not be powered. If you consult the wiring schematic you will see the pin it comes through and you can check the voltage there when motor is running. But, first thing is to find that fuse. FYI, on my 400 that system has been bypassed so that the K1 relay is not even used. It is just "known" to run the engine for anchor retrieval, rather than enforced by the electrical controls. Edited by DJgun - 18 May 2024 at 23:34

	Hi DJgun. Had to leave the boat for a few weeks because of work, but will chek that as soon as im back, sounds like the fuse could be the problem. Thanks again for your help, Frodi

	I like what DJgun has suggested. That relay is more trouble than it’s worth. The 588 has no such device. The problem is that you may need to use your windlass or thruster in a situation where your engine has suddenly died or even if just the alternator has quit. It can put you in a precarious situation.

	Hi DJgun. Actually the problem as you suggested was a blown fuse in the engine room. Thanks again for your help.

	Hello all. I have read this thread with great interest. I have a 2008 430 and my bow thruster has been working itermently. I have replaced the 2 Amp fuse at the engine, and he fuse that leads to the relay in the electronics cabinet. The lights on the switch panel do light when the engine is on. I have cleaned all contacts on the thruster unit in the bow compartment. I have cleaned the contacts on the wire connectors at the control switch at the stbd helm. When I try to switch on the bow thruster at the helm control. Black button and toggle switch. Nothing happens. No beeps nothing. Do you have any ideas what may be wrong. It has worked and then not worked for the past few months.
	Adventure awaits

	I’m also greatly interested in this post as my windlass (anchor winch) recently failed to retrieve the anchor - and retrieving a 20 kg Vulcan anchor with 80 feet of chain by hand is something I don’t want to do again! I opened up the windlass to check out the contactor and noticed a defective spade terminal so I replaced the Lewmar contactor. Unfortunately, the windlass still will only lower the anchor and not retrieve it. There is a post with the 430 electrical schematic but I’m unable to view it. Fuses appear to be ok but who knows as the wiring on this boat is difficult to trace due to all the harnesses. Wondering if anyone has 1) a PDF of the electrical schematic and 2) thoughts on why the windlass won’t work in the up mode?
