Hello Forum, my Hanse 312 buildt 2004 is equipped with the RPM meter (picture attached) which also shows the engines operation hours. Since some time the indicator of the RPM meter often remains on 200 RPM even though the engine is stopped. The new fault now is the hour meter which only shows fragments of the digits. So, I have to substitute the entire meter. The data on the instrument are: "Siemens VDO trading Nr. 02 12 195 12 / 24 V" VDO told me to contact Yamar. So I did. But the spare part they offer is quite expensive. Has any one out there an additional idea where I could get such a spare part ? Thanks in advance for your advice.  ------------- Sailbonbon |

Hi, the blank LCD for the hour meter is a standard error. I'm in my second Hanse with Yanmar engine and both stopped to work after approx 8 years. I have a couple of friends with the same problem. However, there is a method to fix it if you are a "handy man". I attach the instruction how to do it. http://myhanse.com/uploads/3797/Repair_of_Yanmar_Tach_updated.pdf" rel="nofollow - http://myhanse.com/uploads/3797/Repair_of_Yanmar_Tach_updated.pdf ------------- Jesper |

We have installed an external hour meter in the Cabin next to the electric panel. The rev counter works mostly correct.------------- y-u.n |

Surprise, surprise, before I followed the repair instruction I searched through the internet and found a later post from the instructions editor. There he mentioned that the hour meter after a while again was faulty. What to do ? This morning I dismounted the instrument and found an easy solution: 1. Loosen the 3 screws you can see on the back of the instrument 2. Before the screws come out pusch them in direction of the front glas 3.Through this the glas will come off and you can take the instrument out of its housing. 4. Carefully take the white connector away from the pins on the plate (see picture) 5. Also take out the smal white plastic piece ( its the end of the cable ribbon) of the connector 6. Spray all the connections with a contact fluid 7. Put everything carefull together. 8. Do not use metal instruments to manipulate the electric parts After this procedure my hour meter shows clear visible digits again. Best regards  ------------- Sailbonbon |

My hour counter (Yanmar Panel , 2006 315) works only in summertime  , whet the weather is dry. Now I decide to install (by my mechanic) a analogic hour counter inside the motor box, togheter a Emergency engine starter, if you lose or broke the key, or if the electric panel make default. ------------- Alessandro Camerini 315#526 Marina di Salivoli, Piombino ITALY |

If you have to change your RPM meter You can buy any kind of diesel RPM meter Even on e bay ;-) You plug in on the "W" of the alternator Over and out ------------- Not only those who wander are lost I've learn that the best way to learn about people is to sail with them |

Hi Ta'I Miti I too would like to install a new meter and your solution seems ideal,however knowing little about electrical equipment I am hoping a picture or basic sketch will help me to identify the "w" terminal Engine is 3ym30 with 60 amp alternator coupled to sterling regulator Thanks Keith |

Hi, where from did you get the + connection for the hourmeter? From the key switch, the alternator or somewhere else? thanks ------------- Hanse320 - Hull#127/08 - Wheel - ST headsail - Yanmar 3YM30 - SD20 |

Here is one replacement tacho and hour meter that fits quite well in the Yanmar B-panel. It is from swedish biltema, but the same meter is available from other brands also.   BR Mikael Hanse 315 - 2006 |

Too bad I didn't see your post in advance. I'm a frequent visitor to Biltema but never noticed that they sell things like this. I took the hard way and got a replacement tacho from a Yanmar dealer. The brand is Italian - San Giorgio S.E.I.N. and it's for "W" signal from the alternator. I took the unit home to make the hour meter run to the old value. I thought by applying 12V to the tacho itself it would start counting. Nothing happens, it's still at 0.8 hours. Do I need to apply some kind of voltage, or frequency, to the tacho input to get the hours counting? ------------- BÄSK, Hanse 370e #82 from 2006, Yanmar 3JH4E/SD50, 3-blade Flexofold, RMC(Lewmar) 185 Bowthruster, Vulcan 9, Simrad+B&G instruments |

Hej, my front panel has been damaged and I tried to get a spare part in Sweden. They told me i have to replace all of it. My old instruments are useless according to them. About 1000€ just for a piece of plastik. To repair the Engine hour meter is easy. You will find a Youtube video to fix it. How much dit you pay for the original Yanmar spare part? (front panel incl. instruments) Regards. Vetnix

If it's the hourmeter that is not working you can by a replacement LCD here: https://www.boatstuff.se/display-timraknare.html Hours are stored in the tachometer so no calibration is needed. Fits both Yanmar and Volvo. 499 sek is 50€. If you have some skills in electronics and software you can build your own replacement using an Arduino and a oled display for much less. ------------- Jesper Hanse 400e |

I actually only replaced the RPM/hour instrument, not the whole panel. The instrument was damaged by moisture - some times the RPM didn't move and the hour meter was at the end never visible. I tried the method found on Youtube but I was not successful. The Yanmar replacement part (Italian brand now) works well but cost a lot. I would however recommend the Biltema instrument for pricing reasons and not replace the whole panel if other things works OK. For the winter I brought the whole panel home to make the hour meter run to the correct value. The problem is that I can't get the hour meter to move just by applying 12V to the instrument itself. Do I need to also have some frequency on the "W" input? ------------- BÄSK, Hanse 370e #82 from 2006, Yanmar 3JH4E/SD50, 3-blade Flexofold, RMC(Lewmar) 185 Bowthruster, Vulcan 9, Simrad+B&G instruments |

The Biltema webpage actually shows that article WITH hour meter. I got a response from the Italian manufacturer of my instrument - I need apply BOTH 12V power and a frequency to the "W" input to make the hour meter run :). ------------- BÄSK, Hanse 370e #82 from 2006, Yanmar 3JH4E/SD50, 3-blade Flexofold, RMC(Lewmar) 185 Bowthruster, Vulcan 9, Simrad+B&G instruments |

Hej Vetnix. Actually Biltema has no hour meter in any picture of the tacho. Not even on the box my Biltema tacho came in. I just found the box while cleaning my garage. But in reality my tacho(25-8039) has a hour meter. So you need to check it from the actual product on the shelf in Biltema. mvh |

Hi all, Previously I replaced the LCD hour meter (thanks to the forum !), works fine. Recently the tachometer started working intermittently, and then stopped working entirely. In order to not have any potential issues with generic tachometers from chandleries, I decided to buy a Yanmar unit (almost 300 Euro). However, I can’t get it to work The new meter has 4 wires, the old one 5 (2x black) Yanmar dealer saying they are connected inside the unit (probably just the ‘minus’ wire). They told me to set the pulse at 10.29, with the pushbuttons on the back, which I did. The LCD display works, the background lighting works. But the RPM needle doesn’t move. When I turn the switch to ‘on’, I feel and see the needle vibrating for some 3 seconds, then it sits still. When I turn the switch to start, I see and feel the needle vibrate again, but then it stops and stays at ‘zero’. The (original 60A Hitachi) alternator works, charges the batteries. Anybody any idea about what could be the issue ? This is a picture of the old and new unit.  Peter ------------- Hanse 400e "M-square2" #0241 |

To close my own thread. I checked the alternator pulse output with a multimeter set on AC. Showed between 15-16 volts, I.e. then Knew alternator worked. Then followed the orange wire. Turns out the signal didn’t carry between the last black plug in the engine department and the next black plug near the engine switchboard. Connected the tachometer directly with the alternator and it worked. So, will run a new wire directly from the alternator to the tachometer. Following the same path as the original wiring loom. What i don’t understand (or like), is why 1 wire in a factory installed wiring loom became faulty. Makes me wonder about the other 7. I followed the loom and couldn’t find obvious areas with chaff or other kind of wear. Peter ------------- Hanse 400e "M-square2" #0241 |

Hello I've got the same RPM pblm Can you tell me which alternator output you checked and which one was the problem? THANKS ------------- Not only those who wander are lost I've learn that the best way to learn about people is to sail with them |

It’s the orange ‘pulse’ wire. In case your alternator is the source of RPM input (which I would expect with 2004 engine). If not the alternator, there should be a sensor on the flywheel (I have no experience with that but believe it’s the same logic, also orange wire coming from tachometer sender/sensor) I followed the lead of this post on cruiserforum.
