Post by: GSouthee on June 02, 2022, 16:13:52

Anyone know the ohm range of the fuel gauge on a 2 litre saloon.

Cheers

Sorry, I haven’t a clue. But just wanted you to know there is someone listening on the forum. Fingers crossed you get to know.

Gary,
do you still have an old fuel sensor working? In that case just measure the resistance.

Hi Peter

Already tried that, but sender dead. I may have to use an ohm matcher if I get an after market sender.

Cheers

Your fuel gauge sender problem peaked my curiosity. I have a similar problem with mine, but at least the part number is stamped on mine, though I can't get the d...mn thing out of the tank! I usually try and clean the surface of the rheostat which works for a while.

 I searched on AC 2 litre and found the following two sources of information, the later being useful for all AC models. They were www.ac2litre.com which gave me the link to www.holden.co.uk.

I then searched on the holden site for "fuel tank sender". Some of the items have a video explanation basic principles of how they work
e.g. https://www.holden.co.uk/p/sender_for_original_moving_coil_gauges_two_terminal_ , sender for an XK140. Didn't look for one for your AC but maybe you can do an occular comparision or give them a call? They also listed a device to match sender to gauge.

Hope this helps.

Hi Paho

Yep tried Holden no joy.

I can get a choice of senders that will fit but have various ohm ranges. So will probably go for an Ohm matcher.

Great info though from you, cheers.

The joys of old cars.
