Fuel Gauge

Hi:

I just fixed my fuel gauge ...In order to calibrate the needle, do you know what's the range of voltage that the regulator send to the gauge?...I asume 0 when the tank is empty, but when it's' full ??

Are there problems if you bypass the voltage regulator?

Thanks,

Chalito.

 

I dont know the specs but you can map it yourself with a volt meter.The sending unit is just a rheostat(like a dimmer switch for your lights)and the guage is basically the light bulb.Good luck.

 

73 ohms empty and 8-12 ohms full. http://www.egauges.com/ATM_Tips.asp?TipPage=fuellevel.htm

Here's some good reading http://www.mustangandfords.com/techarticles/75259_instrument_electricity/index.html

 

thanks for your answers.

The voltage regulator then limits the fule gauge voltage to 5 volts, I can now calibrate the needle.
