Measure the Supply Voltages Applied to the GSP (A19)

Measure the power supply voltages at the GSP (A19) assembly that come from the
motherboard (A17) assembly. Unplug the wire harness (J3) from the back of the GSP
interface. Check pins 2 and 3 for +5.16 ±0.1 V (see
Figure 6-4).
If the voltages are incorrect, refer to Chapter 5 , "Power Supply Troubleshooting."
