[Amps] {SPAM} Kilovac H-18

[Dan Hearn]

I have had a similar problem with the vac relay in my 77DX. I cured it by
reversing the coil leads. Supposedly the core in the relay becomes
permanently magnetized from the DC . This happened to me only once but I
installed a reversing switch on the rear chassis just in case it happens
again.

Hello:
    I have a Kilovac H-18/12VDC DPDT vacuum relay. I've been planning to use
in a pair 3-500Z 6m amp. Was testing the relay only too find out that it
doesn't make contact with NO contacts. Relay sounds like it is switching,
but doesn't show continuity. Any ideas, bad coil, etc.
