My fuel and temperature guage stopped working in my '67 XR!

My temperature guage and fuel (not gas) guage stopped working the other day. The funny thing is though the temperature guage has stopped alltogether, but the fuel guage is sortof going down slowly but stopped a little below halfway...and thats right after i filled it up and ive been running it on gas since so it hasnt used up any petrol. And there's no leak, i would smell half a tank of petrol leaking out!

Would this be a simple fuse, or something else?

Cheers

Re: My fuel and temperature guage stopped working in my '67 XR!

These gauges won't have fuses in the fuse box.

Temp gauge:

Check the wire and clip on the sender at the front of the block (make sure its not broken/corroded/fallen off/loose etc)

Faulty sender?

Fuel Gauge:

Check all the wires on the sender. Sometimes they can break off. Or being old, the terminals on the plug can get corroded etc. GOOD clean up if req'd.

Last time mine stuck on half, one of the 3 wires broke right at the sender. Geee, I'm getting good fuel economy this week!.....As I ran out of fuel in the middle of knowhere

Possible faulty sender in tank?

Do you have access to a multimeter to check for voltage and resistance/continuity (for broken wires) in the wiring?

Yeah i can do multimeter stuff no worries. Is it the one sender which would handle both these things, or affect both of them?

I think you will find that the "constant voltage unit", usually in or part of the temp gauge is at fault, this item regulates to around 5volts the feed for temp gauge AND fuel gauge.

So will that mean i will need a new temp guage bit, or can i just replace that bit?

You should be able to just replace the constant voltage unit. Some folks upgrade to a solid state item at a fraction of the price. Have a look at this site, it explains how to do it.:- www.stormloader.com.falconccwa/
