When you think of an Engine, Tanker, Wildland, or Aerial device, usually the first thoughts that come to mind are, what size is the pump, or what size tank does it have?
Maybe it’s the size of the motor or how may seating positions it has.
What most people don’t think about is the wiring that your apparatus has to make everything work.
Think about it. Just about everything on a new piece of fire apparatus has a wire connected to it. Headlights, seats, fuel senders, the engine, transmission, pump, warning lights, and on, and on, and on.
Think about repairs on your existing apparatus? Bet quite a lot of them were electrical related.
Multiplexing has helped dramatically, reducing the miles of wires by about half, but there is still a lot of wiring, terminals, and control devices still needing communications.
The picture shown is of a cab with just some of the cab wiring that will be run and connected. Think of your mechanic trying to isolate a short or tracing a wire?
The reason for this commentary is that when you have an electrical issue on your apparatus, remember that your electrical system is the most complicated system on your vehicle, bar none. Have patience, and complement your mechanic when he fixes your electrical issue. He’ll really appreciate it.
