Wiring up Tim gauges
Turbo Mini Forums

Im finally getting round to re-wiring my gauges after a year of not being wired in, but I can't remember which terminals are for what on the gauges. Most of them have 3 terminals, labelled, L, G and S. Im guessing the L is +12v and you would think G is ground but what is the S for?

Cheers

So what about on a fuel gauge, how would that be wired in?

?

L to 12v
G to ground
S to the sender

yep as above,

the fuel sender has a ground spade to it too. when the tank is full the sender will be low resistance (nearly a short circuit) and will make the gauge go up.

But wouldn't wiring the ground in cause the gauge to read full as it would be causing basically a short circuit?

I tried it both ways...i think my sender could be goosed!

Well all the sender is is a verible resistor.

12v comes from the gauge and the change in resistance of the sender will cause the current to rise or fall, The guage its self is essentialy just an ammeter.

To make the circuit both the gauge and tank are grounded, it shouldnt matter if you connect the ground of the sender (probably doesnt even have one, it just grounds straight through the tank) straight to the gauge or use the car as your ground conductor.
