Troubleshooting New Components Theory of Operation/Voltage Regulator - 2
New Components Theory of Operation
New components on the Power Macintosh G3 logic boards and new
strategies for parts replacement make troubleshooting these
systems significantly different from previous models. Take a
moment to read and understand how each of these new components
interacts with the system.
Voltage Regulator
The voltage regulator module regulates the voltage for the partic-
ular processor used in different Power Mac G3 systems. The volt-
age regulator provides an easy way to regulate voltage without
changing specific resistor values on the logic board. When you
replace the logic board, you must transfer the voltage regulator
from the old logic board to the new one. (Note: Always try replac-
ing the voltage regulator to resolve power-on problems before
replacing the logic board.)
