Gas gauge not working? I think I fixed it.
Picture 1
shows the variable voltage regulator I ordered from China (cost $1.15 delivered ) .
Pix 2
Is the back of the dash board cluster. I actually removed a piece of plastic to the left of the hole to be able to align the regulators adjust screw with the hole in the dash
Pix 3
shows the placement of the hole I drilled in the dash
Pix 4, 5, 6
shows the wires attached and the board is tacked in place with hot glue
Pix 7
The adjustment screw is placed behind hole so I can adjust the regulator without removing the cluster.
Pix 8
Wires run thru the hole I cut in the metal can.
Pix 9
Orange wire is + output of adjustable regulator. Soldered to fuel gauge side of cut trace
Orange/wire wire is output of regulator soldered to ground
pix 10 and 10b
blue wire is input to regulator. It can be soldered to any +12 vdc source. I chose to solder it to pin 1
on the pin connector.
Blue/white wire is input. Attach to any ground
Pix 11
shows 5vdc regulator still feeding temperature gauge. I also placed a piece of plastic on the back of the regulator board so there is no chance of grounding out to the metal can
Pix 12
shows where I cut the trace between the two meter inputs so they can be fed by different sources.
I have not yet been able to calibrate the gauge as I do not know how much fuel is in the tank. I will wait until I run out of gas to calibrate the gauge exactly to the E. Then I will see how far the gauge
travels to the F.
I am mostly interested in when the gas is getting to Empty. I will just make a mental note where the Full is.
