    Klipvolt Polarized Suppressor

    Hi Guys.

    chasing one of those annoying intermittent faults that is causing the
    master solenoid to drop offline and kill all electrics in my A23-19. As
    far as I can tell the electrics relating to the battery and master
    solenoid are original. We think we have found a short circuit that could
    have been causing the problem in a strange looking blue device bolted to
    the battery box next to the Master or Battery Relay. This device is
    connected across the battery relay coil field and in the workshop manual
    on the BAC website is shown as a diode device on the circuit diagram and
    labelled as a 'Klipvolt Polarized Suppressor'. (For the engineer folks
    Section 4 page 7. My serial number is MB142).

    OK thoughts:

    I think this was shorted out which would cause my problems with the
    contacts touching. However the device in question does odd things on
    testing with a voltmeter and certainly doesn't behave like a normal
    diode. From the circuit diagram it is obviously there to suppress back
    EMF voltages as the relay de-energises.

    However can anyone shed any light on what this device is, how it should
    behave on electrical testing, and what if any is a modern equivalent.

    Thanks for any suggestions.

    Klipvolt Polarized Suppressor

    Beech SL0614-351 calls for the removal of the S550 Klipvolt Suppressor from the Battery Master Relay, and the installation of a 1N4005 Diode instead; most likely due to problems like yours. We don't have a copy of this SL loaded on BAC, because it apparently wasn't issued specifically for one of our aircraft models (19/23/24/76/77). I suspect it was one of those SL's that was supposed to apply to all models, but which were seldom complied with across the board because no AD was ever invoked. I can't find a copy available as a free download. Please try calling Beech Support at 800-429-5372, and ask them for a free copy. If we can't post an exact copy on the BAC website due to a current copyright on it, perhaps we can at least include a reference to it and the key content. I hope this helps; please keep us posted on your outcome.

    Klipvolt Polarized Suppressor

    Mike,

    You are amazing.

    Means the fix we had come up with is even legal too!

    Many thanks from the land down under.
