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.
Note: To verify the power supply, you need a volt meter.
Verification Procedure
Follow the procedures in the Take Apart chapter to access the
power supply.
Important: 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.
