Could anyone point me in the right direction for a complete re-wiring of a big boy dynamo cabinet. Ive had this for a while and am now trying to get it up to par. the wiring that was in it was a horrible disaster so i need to start from scratch. thanks
 
now for the monitor, anything i should read?

Wiring it up? It's simple - red, green, blue and sync signals (JAMMA games use composite sync), with video ground. You'll just have one cable coming off your JAMMA harness that plugs into the monitor. Might have two plugs (separate sync header) depending on what kind of monitor is in the cabinet. You should be able to tell by what's already there what the pinout should be, if not, check the manual for the monitor.

Power for the monitor goes through a 1:1 isolation transformer. Do NOT power an arcade monitor without an isolation transformer! You will destroy things.

Again, Bob Roberts has a whole article on wiring the AC side of the cabinet

Although, chances are, your AC wiring is OK. Even if it's modified, it should be easier to patch than rewire.

great, that was my biggest issue with the monitor and transformer. will let ya know how it goes.

thanks again

It's really, really simple. Hot and neutral from the wall go to the input windings of the transformer, no particular polarity. Output windings of the transformer are two pins - no polarity, they go to the input on the monitor. Metal frame of the monitor is grounded to earth ground, so is the metal frame of the isolation transformer.

Don't think it is all easy. I just finished rewiring a Dynamo cabinet. F*ing operator wired the switcher directly to the power cord. No fuse, no power switch, nothing. And the ground wire goes nowhere.....:mad:
