J307 Voltage Measurements

Cable W9 connects J307 of the A1 Main Board Assembly to J207 of the A2 Interface Assembly. Table 3-4 provides a quick method of determining if the voltages between these assemblies are within the normal range. If any of these voltages is outside the normal range, refer to the flowcharts to further troubleshoot the circuit associated with the abnormal voltage.
