I'm troubleshooting a new dead cabinet I bought, and finding a lot wrong along the way. The latest - the switching power supply seems to be putting out adequate voltage, but as soon as I plug a PCB into the JAMMA harness, the voltages drop off significantly. The +5V, for example, drops from a solid 5.0V to about 1.8V, and the LED on the supply even goes out.
Is this an issue with grounding, or with the power supply being overtaxed, or both? Any suggestions would be appreciated.
