|
|
1970 type 2
Problem: Gauge stuck at 0/1. With Tank almost full.
Connections:
Gauge +12V, connected to +12volts.
Gauge G, connected to brown wire.
Measured +12V at +12V gauge connection.
Measured +4.5V at G connection.
Disconnected G wire measured 5 ohms from wire to GND.
Shorted G connection to GND, gauge at 1/1.
Reconnected G to brown wire, shorted at T1(also brown wire), gauge at 1/1.
How can gauge work, and have 5 ohms at G wire and gauge at 0/1 when connected? _________________ 1970 type 2

Hi all, new to this since I got my son's 76 bus after his passing. The fuel gauge is buried at empty. Is there a way to test the gauge? I have the intsrument panel off. Not going to worry about the sending unit. If that is an issue I will just track mileage. |

Sorry for your loss.
There is a wire connector in the right rear wheel well. Ground that terminal and the gauge should read full with the key on.

19/20 it's the sender. The friction eventually rubs through the wrapped resistance wires, hopefully you may find a pre-cut access hole to swap the sending unit out. |

Unfortunately, no access hole. Good thing I am good with math. |
