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.
