Flashing F2, fuse replacement

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Dear all,On my 588 the pump with the hose is controlled by the F2 position in the wurth display. The F2 led flashes and the pump doesn't switch on, leading me to the conclusion the fuse needs to be replaced.

...but which fuse? I read the manual and the diagram, I tried to guess and test few 5A fuses in the proximity of the flashing led but they were all ok. 

How to know in general which fuse needs replacement, having a flashing led on the wurth? 

I read on the thread the suggestion of testing then all, but it seems to me bizarre to go by trial and error when the information could be summarised in a single picture. I am tempted in spending few hours and doing it myself but it must be available already...

	PZucchel, You are looking for a 15 amp fuse which is blown. It should be on the outboard of the stern side of the Wurth panel when you pull it down. There is a drawing which shows the fuse details and I can email it to you. PM me your email address.

	Hi Wayne, I actually found the magic document! It was posted here on the forum, but it's not past of the original hanse manual... The fuse is the 30A, impossible to know without this magic file.... Thank you anyway!

	30A? This is something like an autohelm controller, rather than a roving bilge pump. What does the diagram say? My F2 is not the roving bilge pump but the anchor washdown pump. Clearly not 30A.

	In my hanse 588 I have a 25A pump connected to a 30A fuse. With the chart fuses vs. Buttons I had found in this forum I have replaced the broken fuse and now it is fully functioning.... The pump is connected to a hose in the center of the boat. Thanks to all! Edited by Pzucchel - 30 July 2020 at 07:57

	If they are blade fuses you could replace them with glow fuses, just like a normal fuse but with an inbuilt led which lights when the fuse blows. They are not expensive and I have replaced most of mine now, it makes it so easy to find the broken one. Many different suppliers I think, here is one example: https://www.12voltplanet.co.uk/standard-blade-led-glow-fuses.html

	Hi Guys, I have recently become a 575 owner , I’ve managed to blow the Nav Light fuse attempting to fit a new LED port side nav light! The original or maybe not wiring was unconnected in thestanxion , I moused a wire vertically from the crew cabin connected the light, then screwed in the bolt at the lower end of said Stancion, of course the way I. Which Id moused the the wire meant that as soon as I tighten the bolt into the Stancion it blew the fuse! So my first question is having found the swathe of fuses on starboard side lower than the chart table, how do I identify which fuse has blown, no diagrams on board, secondly how do you wire the nav light without going through the centre of the bolt on the lower end of the stancion! Any and all help would be appreciated!

	It MAY be in the diagram that I and others have posted, but you might also find that the best way is to look at the wires coming into the "Hanse Board" below the Nav station. Even if the diagram is wrong, the wires are usually labeled as to "Fusion Stereo" or "Mast Bilge Pump". This tends to be the definitive answer. I started with the diagram and then used the wires to update the diagram. Another good move is to put "glow when blown" fuses into the slots. These are fairly cheap at AMAZON or somewhere else and its easy to see which fuse is blown because they light up. I swapped all the ones on the WURTH panel and below on the HANSE boart because I spent many hours on my back trying to check out fuses 1-1. No more.

	Hi Rick, thanks for the reply, where on this forum is the wiring diagram? Or perhaps you could send it to me! Like you I’ve been on my back for 1 hour, underneath the chart table as well as popping the 12v DC panel , can’t find a blown fuse anywhere, although when switching Nav lights on the led flashes showing fault! Any help would be appreciated Thanks Clive

	Here is the layout of the HANSE board and of the 12V WURTH PANEL (at least to the 90% level). As I said, the wire labeling tends to override all of this. As well, things changed from year to year. This wasn't accurate for my 575 (new in 2017) but it was close. If you send me a PM with your EMAIL address, I'll send you a link to what manuals I have. I put together a folder of all the machine readable versions and printed them all out in a divider to keep on the boat/ Hope it helps!
