I think this 55ohms might be nonsense. I tested my 60's gauges, apparently the fuel, oil pressure and temperature gauges should all be 55ohms, yet they are all about 27. None show any signs of damage and I know the fuel gauge worked before I took it apart, can't remember the other two.Did some testing.
Warm engine, checking resistance on the sender according to the manual.

My cheapie multimeter showed 111ohms. Sender probably good.
The gauge was a little more vague.

I’m a bit tired but the first step is throwing me off on how to do this.
Measuring the gauge resistance, 18ohms which is definitely below the range. I’m not electronically smart enough to know if that would make the gauge work or not.
I’m not sure how to setup the the first test.
Also checked online for the gauge. Found a few part numbers but not sure on those. All of them showed up NLA on partsouq although that doesn’t mean that’s the case.
Not sure if the Bj74 is for a 24v or 12. The FJ73 I assume is 12v.
8324390K00 BJ74
8324390K02 FJ73

Could it be an erroneous spec for a 24V system? I'm not very experienced with electronics but I know that if a component flows the same current at 12V as it does at 24V, the resistance must be half, which is my 27 ohms. Not sure if there are different 24V oil pressure senders, coolant temp sensors and fuel level senders, but off the top of my head I would say no, as they are just passive resistances in a circuit.
Not sure if I understand correctly what is the info gap (it quite late at night here...) but the 24 volt sending units are designated for 24 volts (at least the oil pressure unit)That’s a great thought. I had wondered about the manual and 12v vs 24v, the but it wasn’t mentioned that I saw and I’m not smart enough with the electrical magic to know.
I did get a new sender, it’s on the way so hopefully I can rule that out. It’s cheap enough to try anyways.
I also got a test light to check since my other one is packed away. Plugging it into the sensor wire and turning the key on, the light flashes.
Found this on mud about 40 gauges: plus the later 40s and BJ74 use the same sender.
The sender is variable resistor. Being a Temp sensor or Fuel sensor the principle is the same. The resistance changes and thus the current in the circuit and thus the position of the needle.
To work on this cluster you need a analog Volt and Ohm meter. Why…..?
If you are looking for a bad contact, ground, intermittent problem, the needle of a analog meter reflects what happens. A digital meter is flashing digits and you have no idea what’s happening.
If you run the test with the light bulb, the manual says that the bulb will flash after a few seconds.
So at this point the light is flashing and my gauge shows 27ohms. Looking like it’s just the sender.
Just checked quickly - you are correct. The pressure sender 83520-60010/-60011 is used only on 12V models.Not sure if I understand correctly what is the info gap (it quite late at night here...) but the 24 volt sending units are designated for 24 volts (at least the oil pressure unit)
Hope it helps
If Not....disregard

What lake is that??No sunset
Took the middy on holiday to Fraser Island. Had some stubbys, dodged some skippys and headbutted some men in grey suits….

Isn’t that what all aussies do?
Or maybe I just went to the lake on Father’s Day…

Other side of the lake. Didn’t explore a bunch, we were on a mission to cook steaks.

It appears the leak on the one side stopped but another has popped up. Should have used FIPG and gasket I suppose. I guess I’ll try the bandaid spray until I I can pull it all apart again. I’ve got 2 timing belts on 2UZs to do first.

Yeah it’s a fun place if you are a lake person.That was my guess. I've actually never been up there. Might have to one day. In fact, there's a river in the Sandhills I want to canoe, so maybe I'd stop at the lake on the way.
Lake McConaughy. 100 miles of shoreline.
22miles long, 4 miles wide.
Lake Powell. 186 miles long and 1,960 miles of shoreline at full pool.
....You forgot about "roundin up some sheila's"No sunset
