Can I ask, this board, what purpose does it serve?? Is it power?

Also, will the readings be fine by just touching the front of the points? Or do I need to actually touch the tip to the top or inside of the points please.

The big transformer behind this board takes the mains voltage and breaks it down into the various voltages. (note the label above the board). This board protects the game with the fuses and converts the AC mains voltage to DC for the various voltages with bridge rectifiers.

The front of the test points are insulated. Put your probe inside or on top.

Perfect! Thank you!
