    Unhappy Stuck solenoid

    My solenoid seems to have got stuck in a locked position. For sure, it is not firing anymore and not "clicking" either.

    I think it has been caused by some saltwater coming in through the oxygen feeder connector. I have taken the solenoid off from the head and rinsed it in fresh water hoping to dissolve any salt cristals, but no luck!



    Does anyone have any idea how I could fix this?

    Want to go diving again...

    Thanks!

    have you taken it apart? It is very simple mechanism.

    Re: Stuck solenoid

    1) check battery
    2) chek IP of Your first stage
    3) try connect baterry direct to solenoid

    it's depends from many case - how old Your solenoid? do You have spare to be shure? Simple way - connect another solenoid and if it works ... change it

    Jaksa solenoid removal.pdf

    I have included a step by step procedure for disassembly and reassembly of the Jaksa solenoid.
    If you feel you had contamination with salt water, it will be best to disassemble your solenoid and give it a bath in a ultrasonic cleaner.
    There are 3 o-rings in the solenoid 2 hold the magnet in place and one at the base of the plunger assembly to create a seal. Be carefull of the one at the base assembly to not damage it. You can reuse it ( I have done so at least for 3 services) if it is damaged then you will need to contact ISC and request a replacement these are not included in their 0-ring kits.
    Hope this helps it is quite simple to do.

    Re: Stuck solenoid

    Hi Gabe, where is the step by step?

    I have taken the solenoid part apart from the Jaksa part (if you understand what I mean with this). The Jaksa part seem to be working when I power up the unit, but not the solenoid itself. Can I take this further apart?

    Thanks all for answering!

    Re: Stuck solenoid

    the only additional comment I'd add to Gabe's step by step, is that newer Meg's include a cintered filters to help prevent any gunk from getting into the Solenoid in the first place...

    If you don't have it - might want to consider getting one added next opportunity your having something else done.

    Yes follow the instructions and you will be able to break it down into all components and it will be easy to clean and reassemble and I am sure it will work just fine.

    Re: Stuck solenoid

    It sounds like your assumption of water ingress could be correct.

    It only takes a small amount to get in and stay there and it will corrode the plunger in the closed position.

    The remedy....New solenoid.
