Allison 1000 Nsbu Wiring Diagram



For those who own a truck with an Allison 1000 transmission, it is important to know about the NSBU wiring diagram. The NSBU (Neutral Start Back Up) switch is located on the side of the transmission, and is used to switch between reverse and forward gears. It is important to understand how the NSBU works and how to wire it correctly.

The Allison 1000 NSBU wiring diagram is relatively straight-forward. It consists of two components: a power module and an input module. The power module is the part that provides the power for the transmission. It contains a fuse, circuit breaker, and a 12-volt supply line. The input module, which connects to the power module, is responsible for activating the gear switch. It contains a relay, a terminal, and a three-position switch.

When the NSBU switch is in the “forward” position, the power module supplies power to the transmission. When the switch is in the “reverse” position, the input module sends a signal to the power module to turn off the power to the transmission. This prevents the vehicle from inadvertently shifting into reverse when driving forward.

In order to properly wire the NSBU switch, all of the wires must be connected to the correct terminals. The diagram shows which wires go to which terminals. It is important to note that the inputs from the power module must connect to the correct terminals on the input module. If the wires are not connected to the right terminals, the transmission will not operate correctly.

Once the wiring is complete, the transmission should be tested to make sure that it is operating properly. If there are any issues, they can usually be resolved quickly by checking the wiring diagram and making sure that all of the wires are connected to the correct terminals.

By following the guidelines in the Allison 1000 NSBU wiring diagram, you can ensure that your transmission operates correctly and that you are using the switch correctly. This will help you get the most out of your transmission and keep your truck running smoothly.
