Hi. I’m hoping others have solved this. I have a new set of bow thruster batteries and the worth panel is reading 99 volts. They test fine at 24 volts. Is there anything I can do to fix this, is there a setting in the worth panel? Thanks, -Chris |

The wires sensing the voltage of all batteries are attached to the Wurth panel somewhere here, you can check the voltage at those contacts to see what it reads. I would simply turn the power to the Wurth panel off and then back on, it should reset and hopefully will show everything correctly  |

Is it possible that the sense wires are reversed ? ------------- Leon / ARCADIA 2018 Hanse 588 Sag Harbor, NY |

If they are reversed or disconnected, it would most likely have happened at the batteries

| Thank you for the replies. I will look at the wires being reversed this week once back aboard and report back. |

Hello, I did validate the proper insertion into the Wurth panel (6B3). The panel only has a positive connection, so no wires to reverse. Open to additional thoughts. -Chris |

Did you check the connections at the bow thruster battery location. At the battery terminals. ------------- Leon / ARCADIA 2018 Hanse 588 Sag Harbor, NY |

| If you are sensing correct bat voltage in Wurth, swap the sense wire between thruster bat and house/engine bat to see what it shows. It doesnt look logical that your other bats would show the right voltage but not the thruster one |

If the batteries were recently replaced then look there for the most likely error. ------------- Leon / ARCADIA 2018 Hanse 588 Sag Harbor, NY |

Voltage show 24.6 at the panel… but the wurth display shows 99. I tried switching to the house battery slot , but it also will not read properly as it’s looking for 12v. |

| Maybe you need to reset the menu display to set the correct voltage range. Here are the instructions: uploads/7630/Würth_DC-Panel_V2_EN.pdf" rel="nofollow - uploads/7630/Würth_DC-Panel_V2_EN.pdf |

Hi My consumer/house batteries does not share a common negative with the thruster batteries. That was not easy to detect. And gave me trouble when wiring a remote for the thruster. Perhaps a similar issue you got? As mentioned above try measuring near the battey or extend the negative when measuring.

Yes. The thruster 12/24 charger and the 12/24 converter (controller power) both have isolated grounds. ------------- Leon / ARCADIA 2018 Hanse 588 Sag Harbor, NY |
