Test points are small metallic pins on the analog servo module circuit
board. Hardware troubleshooting and testing for proper wiring can begin
by testing for proper voltage or signals at these pins.
Test points are labeled with the letters TP followed by a number.
Figure 4B.34 shows the location of each test point. Table 4B.K lists the
test data of each test point.
