Ha! That is funny. That link you posted just took me to the Dropbox homepage.

I didn't think this measurements on the relay pins sounded right so I measured some with a caliper, those are the 2 width numbers.. The Finder measure...

I have some old Otis adjusting manuals that say to set neutral with 2 "test brushes" or make your own by filing brushes to a point exactly on the cent...

What are you using for a flasher? What is the flash rate and is it adjustable?

I think the inductive reactance that causes the voltage drop across the field coils isn't accurately measured without a changing voltage. The same rea...

Do you have blue relay bases on the 2407MC or SCRB?

What program do you use to make your wiring diagrams?

That is debatable. For the most part, Thyssen considers them interchangeable but the fact is the Finder relay's pins are at least twice as big as the ...

That looks right to me! You may consider making room for both a Finder and a Schrack relay base like the TK pic I posted.

So you have a pattern to the field 4 EA from 201 to 121? If you do but do not from 230 to 121 on the 5EA and you have swapped every board then I would...

Sounds like you are not getting a pattern. I'll have to look at a print.

Ya, I don't see why not

Ya, definitely not going to pinpoint which contact but to find a smoking gun on an intermittent contact failurehere it is workingThis is with a N/O wi...

What do you think about this for a fully automatic relay tester?

Maybe I have that backwards? Is it an HD-03 or -04 harmonic operator with the plastic bands on the shaft? Is there an SPI loop expansion board connect...
