    Looking for the correct condenser / capacitor for my 1936
    Neptune twin with the Eisemann Model 72 Magneto.
    I thought I read somewhere where a .14 mfd condenser
    is correct, but I see guys selling generic condensers
    rated at .22 mfd, stating that they are correct.
    Anyway, I was wondering if anyone has been using
    the electronic "caps" and fitting them in the old can
    with success. I know there was quite a discussion on
    the old board, and saved some of the notes.
    This note, references a cap rated at .15 uf, and
    says it will fit in the old condenser can.
    Anyone been using this cap, and what’s your
    results? Thanks, TG
    ===================
    Read below for a factory rep recommendation, Will fit inside an
    old cap can too!
    Subject: RE: TECH-SUPPORT: MKP1839 datasheet
    We propose

    MKP1839415084HQ (MKP 150nF ±5% 850Vdc axial , 400Vac , 10×31.5(DXL) , dv/dt
    – 1000V/us)

    My Mercotronic manual states that of the 6 Eisemann condensers listed:

    H-22-910
    H23-470
    H24-235
    H24-924
    H26-982
    H28-090 ALL ARE .17-.22 mfd…your 72 MODEL MAG EITHER 72A, B, C, (D, DA &F) all coils when checking with said MercOtronic, should have continuous spark at of below 2.0 amps Secondary Continuity is between 40-60 min/max

    So any cap between .15 and .22 will work spot on..

    Hope this helps

    Regards

    Richard

    Richard, Thanks for all your time and help!
    Looks like my usual Briggs & Stratton condenser
    would work. I would like to play around with
    those caps someday and put one in a vintage
    condenser can for fun.
    Thanks, TG

    Garry, glad to see you still have all your data!
    I’ll check out the Echlin RR176….. probably easier
    to find than the B&S condensers I was using.
    Thanks!

    Hey Bucc, depending on how much room you have under your flywheel, try the Orange Drop or Vishay caps at the proper uF rating. They work.

    Mumbles, guess I should buy an assortment of caps and
    start trying them. How do you mount your caps so they
    don’t move around, or vibrate, or is that not a problem?
