Can the KS relay be removed from the machine simply by unplugging a jones plug? If so, maybe remove the KS and examine it under a good light, try to advance it by hand. Compare it to:

Anything misaligned, out of spec?

Read the info regarding servicing an AS relay and then decide... go slow, maybe clean and then *lightly* lube the circuit cards... is the action any easier? If not, take the next step...

Those cards are definitely screaming for a good degreasing! As cash_riprock suggests, alcohol will do the trick.

They could be so gummed up that they could be binding up the mechanism. Also the switch stack riding on the cam in the center of that relay can be contributing to the problem.

Observing the unit while working the mechanism by hand should give you some clues.

Also... forum search can be your best friend

Also also... take pictures while you work... they can be a big help.

Quoted from ChipS:

Thanks for the offer, Lee! And I may eventually take you up on it, if I can't get it working.
Quick question: I've never cleaned one of these before, but I do have a scotch brite and rubbing alcohol. Should I gently scrub the entire board (outlined in yellow)? And then put a tiny bit of superlube on the area in the red circle, where the arm traces?
[quoted image]

Certainly the red circle should get the treatment you describe... the rest of the yellow area is optional. If you do the outer area, an old toothbrush might work better.

Scrub with alcohol until clean, repeat on other side, dry both sides, lightly lube both sides, test the action and report back....

Here's the note on servicing these relays, 2nd paragraph from the bottom details the adjustments for that switch:

Quoted from ChipS:

....
Could the issue by the armature spring? Perhaps it's not firm enough to push the armature back up when the coil de-energizes?
[quoted image][quoted image][quoted image][quoted image][quoted image][quoted image][quoted image][quoted image][quoted image][quoted image]

A possibility, but clean, adjust the switch and re-check first.

Adding the cleaned/lubed circuit cards and wipers to both sides will also increase the drag on that armature... a new spring may be considered after everything is cleaned, adjusted and re-assembled.

Well done! Looks like it's right off the assembly line!
