Digital Gauges & 7V regulator

Post by wingingit1 » Fri May 18, 2018 7:31 am



Hello All,

I'm putting an acewell digital gauge on my 75 GL1000 and currently hooking it up to the temp and fuel gauges. The acewell specifies only a resistance 10-1000r for each sensor.

From what I can tell, the 7v regulator is to power the stock gauges to read the same resistance.

Therefore, I believe that I can wire the acewell directly to one end of each gauge and the other end be the frame ground. Then i could ditch the entire 7v regulator.

Am I missing anything and does this make sense to the more intelligent electrical GL guys?

The 7 volt regulator provides a stable, solid 7 volt reference to the input meters. The "ground" of the meters is sent to the sensors, which provide a resistance to ground, depending on the fuel level/temperature.

If you are using a digital replacement, you would remove the 7 volt regulator, and connect the new meter directly to the wires going to each sensor. The meter should provide its own power, and measure the resistance between that and ground, through the sensors.

Excellent, that is exactly how I thought it worked. I'll update once I replace the temp sender. Its reading continuity so have to tear the carbs back off again to get to it....
