    B&G VHMU Wind Angle Issues

    That's an interesting question. Will try next time I'm at the boat.

    B&G VHMU Wind Angle Issues

    Yes, reset to factory settings and no joy. Was really hoping there is some obscure setting I'm missing that is hosing things up but haven't found it. I think since the blue wire consistently shows zero volts at the WebSocket means something is amiss with the CPU.

    B&G VHMU Wind Angle Issues

    Thanks, pursuing a warranty claim with B&G for the H5000 CPU. I'm told an alternative would be to get an Analog Expansion Module, plug the MHU into that and bypass the CPU connector. Agree that the instruments can be distracting but since the boat came with all this stuff, I'd like for it to be working. Violet/windspeed is okay, just included it for completeness.
  4. I'm hoping for a B&G wizard to chime in with advice or a fix for my wind angle issues... I've got a J/88 with a full suite of B&G instruments including an H5000 Hercules and 810mm VMHU. I recently had the MHU refurbished in Fort Lauderdale by Wheelhouse Marketing run by Jake Marantz. They replaced the entire cable due to corrosion and the wind speed bearing. The PCB was deemed good. It checked out on their bench and as I moved the wind vane, AWA changed correctly. When I connect to my boat, the wind angle is not correct as AWA, TWA and TWD are all off (sitting at the dock, using a spare cable). To try and troubleshoot I measured voltages at the junction box and the cable that plugs into the H5000 circuit board. I get good readings at both locations which tells me voltages are getting to the CPU. HOWEVER, using the B&G Websocket, the voltages displayed there are not the same as read with the multimeter. Blue is zero and Red and Green are different although perhaps in the ballpark. I did this for zero and 90 degs wind angles (measured by eyeball). You can see these in the attachment. I've confirmed the source selection for Measured Wind is the MHU and the MHU alignment is 0.5 degs. I've also tried reseting the CPU numerous times, no change. Open for suggestions before I throw it all overboard and go back to a windex and compass.

    The watch of a yachtsman? Which one...

    I used to race J/24's with one of these back in the 90's. IIRC, you set the bezel at 3 and 9 o'clock to be the headings for the start line. Then 12 o'clock is the wind direction for a true line (in the picture above this would be 0 degrees). Anything other than 12 o'clock represents the favored end of the line.

    j/88 mast base for haul-out

    Dan, I've removed my mast numerous times after hauling the boat and have only removed the thru-bolt #1. Used a crane to lift the mast each time. I'm sure either method will work.
