    I've never had five solenoids go down at once, but Weather-Matic has been
    the biggest disappointment in solenoid history & has been reticent to cop to
    it. By rights, all these I replaced today should not only be replaced, n/c,
    but my labor should be paid, too. WM is warranting the solenoids, but Hank
    gets to decide whether to bill the client for my time. You guys replacing these
    p.o.s. solenoids with the S24BSAK...be very careful, it has brass threads &
    it's easy to cross-thread. Color me p****d off. :hammerhead:

    In reply to my own thread...on re-testing the five solenoids removed today, I got, in OHMs, 10.5, 4.3, 10.9, 3.6, but on the fifth one, got 26.1, which should indicate o.k.
    I bet if I put that back into service, once it heated up, I'd show short again, though it
    could have been a bad King "blue" connection, which I noticed were hardening & turning
    to powder. Global warming?

    I forget, what was the time period given by W*M for their solenoid woes?

    Don't install WM stuff but thanks for the heads up.

    Just talked to my distributor about it....WM voided "no quibble" replacement
    last year. Now, we get to return the crap, the branch sends it to FIMCO for
    evaluation, we get billed for the new ones until FIMCO signs off. My brain
    hurts...I need a :drinkup: & a smoke.

    You might try #5 with a current meter, and see if there's a change.

    Good idea. Any suggestions as to the best?

    I dunno, whatever you got that can read AC amperage, which is the least common item you'll find on multimeters. I suppose you could be gentle, and use a lower voltage, since a bare solenoid isn't getting any water cooling.

    I've seen failed solenoids when the p.o.c. was shut down, but not the clock, causing heat
    without the water cooling. If I was a younger version of myself, I'd have a test bench
    to really see what happened to the solenoid and what caused it.

    I've used clamp-around ammeters for solenoid diagnostics, but solenoids draw less current than they used to, and low-current ammeters are not very common. If you made a bench setup, you could have a one-ohm resistor in series with the solenoid, and read the voltage across the resistor, which lets you use AC voltage scales, which all multimeters have.
