Well, I had a few days away from this project.
My manual says I need two 0.047 MFD 200 V caps.
My retailer sold me 47nf 630 V (as this is the closest they have) and they say they will be okay.
Does 0.047 MFD equal 47nf?
Regards
Gordon.....

Yes! 0.047uF = 47nF.

Thanks Norman.
This stepper really has me beaten. No improvement.
Cheers

Gordon,
Don't feel too bad-- Seeburg built a totally different, replacement for it ! Ron Rich

I have checked everything many times with the same results.
It just steps the letter stepper.
The reset magnet only energises when I manually move the DC Relay.
It never energises by itself.
I must be making the same error over and over.
I think I will leave it for a while and try again at a later date.
If that fails, perhaps eBay for the wallbox. HaHa
Cheers
Gordon

Hi Gordon,
Did you try reading, the Service Manual-- If not-- look at the written description for the "timing circuit"--

Hi Gordon,
Going back to my first reply to you - what's happening with the transfer relay? After the letter pulses are finished, in the gap before the number pulses start, the transfer relay should drop out - that's what "transfers" letter to number. Does it do anything at all - like drop out and then come back in or does it just do nothing? It's one of these copper doped relays for time delay.
Norman.

Hi Gordon,
Is the transfer relay even energizing ?? Ron Rich

Hi Ron,
No, it does nothing.

Hi Gordon,
A couple of things to check - first, is the transfer relay coil open circuit and if not check the RA contact on the letter stepper relay which energises the transfer relay after the first letter pulse.

Gordon,
Dose your stepper cover have a label glued to it ?? Ron Rich

Hi Norman and Ron,
Thanks for sticking with me on this.
The Transfer relay measures 417 ohms. It does nothing, it never moves.
I have checked contacts RA and they are making contact when they should.
The DC relay measures 317 ohms. It also never moves.
If I push the contacts on the DC relay, it activates the reset magnet.
Their is no stepper cover (so, no label).
I have the manual, but no specific reference to "timing circuit".
Cheers
Gordon..

Hi Gordon,
Look in the rear of your service manual-- You may have some "Service Bulletins" there -- Look for the paper label sticker. If NOT there, PM me your address and I'll send you a copy-- How are you assuring that the RA contact is "making contact" ?

Hi Ron,
I found the 'Service Bulletin', thanks.
I am checking the RA contact (letter stepper relay, front, left when facing stepper)
visually and then with a meter.
Cheers
Gordon..

Hi Gordon,
I've had a quick study of the circuit - with the stepper powered and at rest, you should see DC voltage (25V?) at the transfer relay coil. Do you have that? Also the RA contact of the letter stepper switches ground. If you manually move that contact, the tranfer relay should pull in.
It's imperative that you get the transfer relay operational.
Norman.
