I will preface this by saying I'm following the pinrepair.com Gottlieb system 1.
My power supply is putting out the correct voltages of +5v and -12v. When I plug in the MPU and test for voltages at capacitors C16 and C17, I get +5v on C16 which is perfect, but at C17 it tests as +12v. It should be -12v. What would cause this?
My multimeter is set to DCV and i'm testing the C16 and C17 capacitors with the red lead on the + side(top) of the capacitor and the black lead on the - side (bottom) of the capacitor. I'm testing the right way, correct?
