I'm looking for a working masthead unit type 496-10-002. I specifically need a fully-working PCB that fits into the MHU body, as I've got the spar which is in good condition.
Thanks.
Thanks.
Checked ebay, but didn't see it last night, but will keep looking.
Tried Cactus, but no joy for components for older stuff like the Network Wind.
I did manage to get my masthead unit working - there is a new replacement PCB that I bought. Not cheap (£250ish) but it saved me replacing the whole Network Wind system, which integrates nicely with the Network Pilot.Hi. Just wondering if you got sorted or decided to do something different as I am looking for a 496 spar because I have broken the plastic thread off where the wind speed bearing attaches. Thanks Nick
In my system it was the wind direction that became hopelessly inaccurate. Suspect one of the three direction signals started failing which caused the wind angle display to be useless. Speed was fine. I bought a new PCB and it has been running now for a year and a half with no issues at all. It was very expensive for what it was, but I wanted to retain the full B&G Network system with the ability to use autohelm on wind mode. It was also an eye opener how much I relied on accurate wind direction when manoeuvring the boat in the marina! So, so far no regrets about extending the life of my B&G wind display and keeping the depth/speed/wind/auohelm trio working a bit longer. Replacing it all was a factor of 10 dearer...!dje67 I have a B&G networked system, old but generally fine other than the MHU 496 that has decided to pack up.
Last year the analogue readout stopped giving wind direction, but, I still had wind speed. This year, wind speed has also stopped.
Can you tell me, in your case, had you also lost direction and speed at the readout, this being my situation, although the MHU is happily operating at the mast head? And once replacing with the new pcb all was well?
As you say they’re expensive.
Thanks. Si.
Hi. I think I'm in the same situation as you now as my MHU has packed up also. The PCB board had got water on it when the O ring went in the housing. I had a few joints soldered again on the board that had gone bad and the rest got a general overhaul. This got the wind speed working again but the direction just does its own thing now. Mostly points to starboard around 80 to 100 degrees. Did you ever find somewhere that could supply a new PCB for the masthead unit as I have had no luck in finding one ?Gregcope thanks. Yes all spinning and pointing normally. I changed the bearings on it a couple of years ago as it happens and all has been well, until last year when the wind direction gave up. Still had wind speed until a couple of weeks ago and that too has now failed showing zero constantly.
It looks as if the next step is swap out the pcb and hope for the best. Replacement of the MHU is not possible really as they are now unavailable and second hand like hens teeth. Upgrading the system from the B&G network system is not really an option as this would cost a fortune and I'm sailing on a retirement income.
Tinleys basically laughed when I spoke with them.
No, I'll purchase a pcb and hope like crazy.
