According to this diagram if I disconnect the connector to the low fluid switch, the light should turn off completely, since the handbrake warning switch (black/red on switch side, black/blue on fluid connector side) is wired to the fluid switch connector as well.
Not only is that not the case, but my low fluid switch only has two leads, black and black/yellow. When I pull the handbrake the brake light still gets brighter when the fluid switch is disconnected. The diagrams are wrong, or the car is not wired according to the diagrams. The latter was obvious from the beginning.
I jumped the wires in the fluid switch connector to see how it would act in that case... The brake warning light gets brighter, just like when I pull the handbrake. And when I pull the handbrake while the switch connector was jumped, it doesnt get any brighter, since it was already brighter from the connector being jumped.
What this tells me is that there is another circuit turning this light on.
Unless its another light under the dash that is loose or in the wrong spot? Is that even possible?
