How is circuit 3 connected to the fuel pump?
Circuit 3 is the one that runs to the fuel pump (via the Inertia Switch) and delivers the voltage/current it needs to activate. Before this voltage reaches the fuel pump, it has to go through the fuel pump Inertia Switch first. If the Inertia Switch has been tripped, it will ‘open’ the circuit and the voltage will not reach the fuel pump.
