Start by NOT cleaning every contact in the game. (oops, guess it's too late for that.) Seriously, best to track down and fix specific issues in an EM. Cleaning all the contacts means you're far more likely to mess up something that was working fine.

So the score reels all reset to 0 and the ball kicks out, but nothing scores points? Do the flippers work? Pop bumpers? Do standups light when you hit them?

First thing you have to do is check out the timer circuit that controls end of game. It consists of a simple circuit of a transistor and capacitor as the key parts. Test the transistor and replace the capacitor. Test the circuit.

The electrolytic capacitor in the timer circuit has to be replaced if it hasn't been replaced in the recent past. The capacitor holds the game playable and when old and bad just doesn't allow but a few seconds of game play if any.

It isn't possible to match the exact value of the original cap so just use something as close as you can at the same voltage rating. The variable resistor/pot adjustment will adjust out the difference in cap value.

1. Check each of the score reel contacts by manually actuating the reel solenoid. The problem may be that when the score reel is on zero a set of contacts is out of adjustment.

2. There may be stuck switch on the playfield. You will have to go through each playfield switch and check they are open.

3. The large "jones" plugs may be dirty and not making good contact. A brass wire brush will work well on the male plug.

Generally it isn't a good idea to go mass switch adjusting with an EM as it is best to focus on the switches associated with the problem.

This is a good game to learn on being a single player machine.

The left flipper is supposed to turn power on to the machine. To power off, an upward slap to the bottom
hits a switch that powers off the machine.

Check the slap switch, you should see it on on the bottom board. Could be stuck..

There is a relay call the lock relay that should be activated when you hit the flipper button. This relay should be held/actuated all the time until the game is either unplugged or slapped off.

You can manually push this relay and it should hold and turn on your playfield and other lamps so that a game can be reset and played.
