I have a couple lamps out on my playfield. THe lamps are good so I believe I need to replace some 2N5060 SCR's (Rectifiers).

I found info here:http://www.pinrepair.com/bally/babypac.htm that states to find the offending rectifier, "Note the color of the wire going to the problem lamp socket. Then find this wire color on the lamp/solenoid driver board connector. Then trace the connector its corresponding 2N5060 SCR. The lower leg of the SCR can be grounded, and the playfield light should turn on. If it does the wiring from the SCR to the playfield lamp is good, and the 2N5060 SCR should be replaced."

but I was wondering if there was a chart to map exactly which lamp is matched to which rectifier? I believe they are in pairs of two?

"The lower leg of the SCR can be grounded, and the playfield light should turn on." Who do you know which one is the lower leg? Does this mean I can run a ground wire jumper to test these?

Thanks
