How to Ohm-out hopper payboards.

The bottom solder-tabs of your payboard should all be labelled.
Your paytabs are generally 2, 5, 10, 14, 18, and 20 coins for the lower pays, and 50, 100, and 200 for the high pays.
In addition, you have 2 other tabs labelled CO (carry over), and F for Feed.
The Feed is the common to all these other tabs.
Pays work basically like this:
When 50V is sent from the reels (having a winning combination on them), each type of win powers one of the pay-segments on the payboard.
1 cherry will light up the 2 coin pay, 3 oranges light up the 10 pay, etc. etc.
When the payfingers carry the power(?) from a hot tab to the Feed ring (the very innermost ring on the payboard) then that powers the hopper to turn and spit out coins. When the pay fingers step off that hot tab, the hopper loses power and pay is over.  This is simplified version, and others may be able to explain it better.
You can accurately check all this with your VOM set on ohms.  Clip one lead to the F tab at bottom of board.  Clip other lead to the 2 tab (for single cherry pay)  Manually step up hopper 2 times.  You should lose continuity AFTER the second step.  Move lead from 2 tab to the 5 tab (2 cherry pay)  Manually reset payboard, and step hopper 5 times.  You should lose the circuit AS the 5th step happens.  Move to 10 tab, do same thing.  Continue on all tabs to check all pays.
This is a much more accurate way to check your payboard than just 'eyeballing' it.  Sometimes you cannot visually see well what is going on under the payfingers, and a meter will let you know precisely what's going on.  You can also use one of those little circuit testers for automobiles that you can get cheaply from your auto parts store.  The ones with a small battery and bulb in them to check continuity.

This works for your lower pays, however to check the high pays, you will need to clip on to the CO or Carry Over tab to check them.

Hope this is of some help.
