GTV v6 phII fuel gauge wiring
Hello everyone (long time no post!)
I have a T reg, 1999 GTV 3v6 phII.
I am trying to get my fuel gauge working. It usually just shows empty. occasionally it shows a half empty measure but it is perfectly messed up.
After pouring over the workshop manual I think I have worked out that the fuel gauge is wired directly to the tank's sender via two connectors G73a/c and G99b. I note that older GTV's have the wiring via the fuse box and centre instrument panel (Presumably where the resistance value from the sender is "processed" somehow). My fuse box looks like the later model without fuel gauge wires.
Anyway I have tested the wiring from the sender to the connector G73a and G73c and there is perfect electrical continuity. The resistance at this connector (which is located just under the glove box), with the sender connected, is about 200ohms (which suggests to me the sender is measuring some sort of fuel depth).
Problem: when I test the resistance (looking at continuity really) of the line from the G73 connector by the glove box to the connector of the aux instrument panel (pink wire) it registers something like 700k ohms or more.
This doesn't seem right. It suggests to me a bad connection between the G73 connector and the aux. instrument panel connector. If this line travelled via some sort of electrical circuit then maybe 700k is correct but I don't think it does. From the workshop manual I'm pretty sure my car's fuel gauge is wired directly to the sender.
apparently there is yet another connector between the gauge and G73 but I fear it is buried deep in the dashboard and I don't relish getting to it!
I am considering taking a brand new wire and connecting the Gauge connector directly to G73 connector. Does anyone agree that this is fine idea? or am I missing something?
Sorry if this is a rambling, boring post but I would welcome any comments on my quest for fuel gauge functionality!
