So I have a 1962 Williams "3 coins" that is working almost 100% with this nagging problem I have yet to resolve. Any one point features on the game will not score. I have checked all the places on the Playfield that give one point, I think around 15, and they do not score. When I start a game, I can hit the one point feature and it will close the ball gate as it should, but will not have enough power to turn the score reel.
I have been able to get the reel to move if I manually touch the relay with my finger, but only very firmly. If I just move it up and slightly touch the contacts, it will not move the reel.

Here is a list of things I have already tried:

Replaced the coil on the score reel.
Checked all one point features for making contact.
Replaced ratchet mech. on score reel as the original was broken and not closing the eos properly.
Adjusted alternating relay. ( goes between 1 point and 10 points.)
Changed relay spring thinking it might be too stiff.
Cleaned the contacts aggressively with a normal flexstone and a fine metal file.
Resoldered some of the wires on the relay in case there was too much resistance.
Cleaned male and female Jones plugs throughout game.
Swapped the one point relay coil with the 100 point relay coil.
Taken the one point score reel apart about 15 times looking for ??? ...something.
Took a jumper and jumped from one side of the contact to the other and it works great, but nothing from the PF switches. PF switch will energize relay, ring the bell, score reel won't move but I do get slight movement from the plunger, as if it is trying but doesn't seem to have enough power.

Thats about it, so I could sure use some assistance.

I was able to take the old contact off, put on a used contact that I cleaned up, and had to solder it from below. It does work but I would prefer a better contact switch as original.

These are the R type relays, which are the older type used on woodrails mostly.
