Hi everybody, bought a S+ at an auction yesterday. 3 coin single line triple diamond. On my old S cabinet and my S2000 the boards are on the left with the test switch on the front. This has the board in back with no switch on it. The usual place is beside the power switch, right? Nothing there, just the toggle arm for power. 10mhz board and the board it plugs into (don't know what it's called) are both toast. Severe acid damage. The battery had rotted off the board completely and fallen to the bottom. I will need them but I'd like to find the test button. I'd appreciate any help. Thank you.
