Maybe a little WD 40 or some light machine oil

I need to know what machine are you working on? Different era machines have different answers.

i have a bally slot machine . when the wheels are spinning the third wheel is not .

Bally made Fireball in 1972 and 1976
They made Fireball II in 1981 and
Fireball Classic in 1986
some of the manuals can be downloaded for free
from the net just search IPDB on the web

Stick a nickle in it and pull the big handle. (this is not a sewing machine)

I have a eralier 80's upright Bally's Pac Man arcade machine that I got off a freind of mine. They said that they palyed it all the time up to about a year ago. I got it home set it up and pluged it in... and nothing happens. I've hit the start buttom on the inside and the new game button but still nothing... Is there something else that I may need to check?

THIS IS DOCTOR FIX. MY BUSINESS IS GAMING REPAIR. (JUKE BOX=PINBALL= SLOT MACHINES
BOWLING =POKER, FOR 68 YEARS.) IF YOU HAVE NOT SOLVED YOU PROBLEM, I ASSUME IT IS ELECTRONIC, NOT MECHANICAL. IF MECHANICAL , LET ME KNOW, I WILL TELL YOU WHAT TO DO.
ON THE ELECTRONIC, OR ELECTRIC (NO COMPUTER)
THERE IS A BAR MOVES ON TO THE CAM ON TOP OF THE CATCH, ABOUT 3 INCHES ABOVE THE BOLT THAT HOLDS THE ARM IN PLACE, WHEN A COIN IS INSERTED INTO THE COIN SHOOT, THAT METAL BAR ENGAGES THE RATCHET , TO SPIN THE WHEELS. DOES THAT HAPPEN ON YOUR SLOT.? OPEN THE DOOR PULL THE WHITE SWITCH THAT CLOSE WHEN DOOR IS CLOSED (OUT) THESE ARE A THREE POSITION SWITCH.
