The world is now a better place and we can finally stop nagging you :lol

So... how do I use this thing? I plugged in the red and black leads... do I need to have the cabinet turned on to check the connections (continuity?)? I don't think I care about voltages, etc. I just care whether a connection is made when the button is pressed. I took the CP off so there's no power but I'm not sure what I should be doing.

The cabinet does not need to be on (in fact, off is better)
Plug in the test leads
Turn it to continuity ..
touch the two leads together.. the meter should beep..
because a circuit is made..
Now you can test either end of a circuit.. and if there is a connection all the way through.. it will beep :)
If not.. its open..
I'm sure there are at least a few hundred videos on it.. But its the most basic diagnostic tool and you should quickly wish you had this for the last 20 years. :)

Got it. In fact, couldn't be easier (just needed to find the right setting on the wheel of the multimeter). Buuuut... something is seriously weird with the wiring and I cannot figure it out. I took the CP off and started testing things - the buttons on the CP were all responding and the buttons on the coin door were not. OK, this was expected... but a minute later without doing anything NONE of them were responding, including the buttons on the CP, which have always worked fine. This led me to believe that the ground wire wasn't functioning properly and there is a loose connection somewhere along the way so I unscrewed the GND terminal, repositioned the wires and screwed them back in and now ALL buttons are functioning.
Great, right? But if it was just that loose connection then ALL buttons should have been affected but it was ONLY the coin door buttons that weren't registering before I opened it up. I'm afraid I didn't really fix anything but I guess I'll close it up since everything appears to be working...
:banghead: :banghead: :banghead:
EDIT: cab is closed up and working properly. Fingers crossed.

No. Never try to measure resistance/test for continuity with power applied to the component or circuit.
- The batteries in the meter provide the teeny tiny amount of current required for resistance measurements/continuity tests.
- If you try to measure resistance/test for continuity with power applied to the circuit, at best you will get an inaccurate reading and at worst you will damage the meter. :scared
+1 on watching a few YouTube videos like this one to learn how to use your meter.
- The leads are backward at 8:41, but the rest of the video looks/sounds good.
