hazard switch/speedo/fuel gauge question
Nearly finished now!
Does anyone know if the hazard switch on the sierra switch gear can be reversed so it comes on when the button is pressed down rather than when it
pops up?
can someone help me figure out my pulses-per-mile for my speedo? my wheels cover 182cm per rotation, my diff is 3.62, my electronic sender
emits 8 pulses per wheel rotation. I got something like 10082 pulses per mile. - answered
My fuel gauge is definitely working the wrong way round. Is it possible to reverse the signal recieved by the gauge from the sender with some
electricker?
many thanks.

Where is the sender? If it's on the axle/wheel the diff ratio doesn't matter.
1 mile = 160934 cm
160934 / 182 = 884 wheel revolutions per mile.
If sensor on axle, 884 x 8 = 7072 pulses/mile
If sensor on shaft, 884 x 3.62 x 8 = 25601 pulses / mile

sensor is built into the gearbox but its definitely 8 pulses per wheel rotation
so...
884 x 3.62 x 8 = 25601 pulses / mile
thanks

Not without a No Volt Relay. Youll need a relay that closes when voltage is removed. The switch wont illuminate either, so not sure if its really
worth it.

with the smiths/ telemetrix fuel gauge you just unbolt the sensor and arm and turn it upside down and rebend the arm to suit.
