Video Game Repair/Reset Switch for Arcade Machine


I need a reset switch installed in my arcade machine.  I have a Tekken Tag machine and I am trying to install a 100 in 1 jamma board but I can't get it to work.  From what i can figure out on the instructions I need to reset the machine to accept coins to get the jamma to work. There is no reset button and when I bought the game the guy reset it with a paper clip, which I don't know how to do.  It seems like I won't be able to get the Jamma board to work without a reset button. Any help you can provide would be greatly appreciated.  Thanks.


Hi Leo,

While the standard JAMMA pinout does not have a reset button, i'm willing to bet that either the SERVICE or TEST switch is what you need. I've attached a drawing to show you where to connect a button with a normally open switch.

Hope this helps!

I can answer questions regarding coin-operated arcade game questions down to the logic board. Error codes, erratic operation, dead boards, I can help with them all. I can help with video monitors on a very limited and basic level only.


I have spent nearly 20 years as an avid arcade collector, and spent nearly 10 of those years as the lead tech for a large arcade operator, doing work for manufacturers and other coin-operated amusement companies around the globe. I maintain a good sized collection of arcade games, as well as a large inventory of spare parts for a wide range of arcade machines.
