I am currently working on an Allied Leisure Hearts/Spades cocktail pinball machine. I get some lights when I turn the machine on, but nothing on the displays or no action anywhere. I have tested 4.6VDC at the filter cap on the MPU. I know that is low, but it should still function. The fuses are all good, but I notice that almost every connector I pull apart has chaulky-looking pins (corrosion I assume). Can I spray the connectors directly and the AMP sockets on the boards with DeOx-it D5? I have never used this stuff before. I assume it works like contact cleaner, but just wanted to make sure it wouldn't damage the connectors or the board itself on the power supply.
