    What a Day.

    My fathfull netune failing died today after 40 min sailing.Motor Servo and every thing else is working but pump board is not lighting up or responding. any one else have had this issue or now of a fix. finding another board will be impossible now.

    can't see any signs of damage on the board.

    On a plus side My typhoon had it first real test today really please with it.

    I've heard about this problem a few times in the past but I can't remember a fix! I think somebody was offering replacement boards??

    Search on here or try and find a posting on the Dive-In Facebook site, perhaps?

    Otherwise John R is your man to repair it.

    I don't know this particular board but assuming it uses an H Bridge for motor switching, one or more of the MOSFET transistors has probably popped. (It suggests that the original circuit design was lacking protection for the MOSFETS.)

    Again John is your man. He provided advice on this for my proportional piston tank controllers which have now worked perfectly for 5+ years. Neptune are not the only ones with problems in the same area. I was told that Engel also had trouble with H bridges and moved back to relays.

    Failing this, if you are reasonably handy with  a soldering iron you could try replacing all 4 MOSFETs.

    The Neptune seems to be a great sub but has one flaw!

    Thanks David,

    fought i had seen something like this before.

    Found the fault it was a stuck reply(hit it hard and release) was so please i rushed plugging in the 12v power. only if find I put it in the pump side not the 12v side and got lovely magic smoke (track burnt). to be honest I'm glad that happened as now it made me changed it to a esc(i know I will lose the failsafes). But if the relay was sticking I couldn't forgive my self it it did it again and I lose the sub.

    will repair the track and if working I put it on the Typhoon's periscope motor and could use the water detechion part to auto raise and lower them.

    Cheers
    Tim

    So it uses relays. Reliable but a bit clunky!
    Yes replace the track (and the relay?).
