Fuel Sender Connections

[The Old One]

Hi All
Fuel gauge is only going to between quarter and half full
Is it possible i have connections wrong?
If anyone has a photo of which wire goes to which terminal this would be a great help, also any other suggestions before i go the new sender route.
My low fuel light is not working either

Thanks

Tony

If it`s registering something I would think the connections are ok. Like you I guess, the only thing I can think of is a dodgy sender.

Edit - Or possibly gauge?

I replaced the sender and it still didn't register full. Replace the gauge and it was perfect.

When you replace both at the same time, replace the gauge first then you can tweak the lever arm and stop on the sender to get it right before you install it.

It costs nothing to check the connections from sender to gauge for dirty or corroded joints before buying a new sender unit. These looms are at least 30 years old after all.....

I second that. Gauge needle position depends on resistance in circuit which is also dependent on good (clean) connections. At the very least both parts of each connection should be cleaned with contact cleaner with a brush etc. and put a little dielectric grease on them so they aren't as likely to recorrode down the line. None of these connections are sealed like on a modern car. Then there is the problem of the crimped connections that fail to maintain a good grip on wires and wires can break leaving one strand if any making the connection. Soldering connections helps this. Removing these possibilities cost next to nothing and should be done as a matter of course before buying sender or gauge. While it may not solve your problem it will make your car more reliable down the road, especially if you systematically do this through out the electrical system as time permits.

Thanks very much for replies.
Would still like to know which colour goes to which terminal on sender.

Hope this is clear enough, non FI tank ...
