I have an nba jam TE and a Mortal Kombat cabinet both have the power cable connected to a metal thing with the isolation transformer on top of it could someone explain to me what this is and is there a manual on opening this? Picture is attached.
It's just a power junction box. Basically someplace to hold the fuse holder, the transformer, and route some wiring. You can access the inside by removing the screws holding it to the bottom of the cab. There should be no bottom...
