Power Supply Verification

 

The Power Macintosh G3 logic board requires a “trickle” power 

of +5V to start up. If the system fails to start up, follow the 

procedure outlined below to determine whether the problem is 

related to the power supply.

 

 To verify the power supply, you need a volt meter.

 

Follow the procedures in the Take Apart chapter to access the 

power supply.

 

  For this verification procedure when connecting the 

volt meter leads to specific pins, ensure the power supply cable 

remains securely plugged into the power supply 20-pin connec-

tor on the logic board.
