NOTE

An M113A3 shift controller (NSN 3010-01-331-2675 or NSN 3010-01-

245-2442) can be attached to the instrument panel and used in lieu of

fabricating the controller pictured in Figure 2-19. However, use the

schematic to troubleshoot the system.

1. Assemble seven rotary switch section (2) starting with 364/A. Put the remaining six in

numerical/alphabetical order. See Figure 2-19.

NOTE

Make sure leads are not touching unused connectors.

2. Solder a lead long enough to reach circuit breaker number 1 and connect all pins seven connectors

together. See Figure 2-19.

3. Solder a lead on the first rotary switch section (2), connecting pins 12, 1, 2, 3, and long enough to reach

the connector on the side of panel. Label this lead, A.

4. Solder a lead on the second rotary switch section (2), connecting pins 4, 5, 6, and long enough to reach

the connector on the side of panel. Label this lead, B.

5. Solder a lead on the third rotary switch section (2), connecting pins 12, 1, 2, 3, 5, and long enough to

reach the connector on the side of panel. Label this lead, C. Insulate lead from pin 4.

6. Solder a lead on the fourth rotary switch section (2), connecting pins 4, 6, and long enough to reach the

connector on the side of panel. Label this lead D. Insulate lead from pin 5.

7. Solder a lead on the fifth rotary switch section (2), connecting pins 12, 1, 2, 4, 5, 6, and long enough to

reach the connector on the side of panel. Label this lead, E. Insulate lead from pin 3.

8. Solder a lead on the sixth rotary switch section (2), connecting pin 2 and long enough to reach the

connector on the side of panel. Label this lead, F.

9. Solder a lead on the seventh rotary switch section (2), connecting pins 1, 2, and long enough to reach the

connector on the side of panel. Label this lead, G-N.

10. Test transmission controller after all connections have been made using multimeter. See table in Figure

2-19.
