Im after some advice on ID3
i dont have the service board/coin tower so manually attempting to wire up the external harness, and i know the wires marked up below go to the external harness.
I've worked out the service/test and degauss switches
but im struggling on the volume, i can get the front and rear speakers working but only on full blast, even with a pot wired to them, can anyone assist me in how to wire them up so they can be adjusted, i've done this before on the like of Daytona etc with no trouble but i just cant figure out how on this.



I notice mine is wired different to anothe i saw on a youtube clip

and im also missing the 2 jumper settings that one has

Many thanks

Ight be some info in thread linked to below, I know I separated mine out and got rid of the credit donkeys ago so it can't have been that hard

Heres some photos from my ID3 Machine Hope it helps.

Master Cab Slave Cab

Slave Cab Panel that would be inside the coin box.

Many thanks, i notice your master has 2 jumpers but your slave doesnt, also i assume you have 2 separate control panels, may i ask do you know the value of your pot?

Yes each machine has its own control panel. Without it no sound will come out of the speakers. the pot is B5K 10k
