Testing the fuel level sender?

[Baxter]

Does anyone know what resistance readings I should get from the Iltis fuel level sender unit?
My gauge ready very low.
I have bridged the connections at the sender unit and achieved a full tank, disconnected it is empty, I'm fairly sure the wiring and gauge are okay.
I have removed and inspected the sender unit and nothing appears to be broken and there is a circuit through it, I think there must be a high resistance somewhere.
I have looked through the Wiki [as best an English man can!] but couldn't find anything.

Did you read this?



Due to the level (left) the sender unit suppose to have the (right) resistance.
The Wiki recommend to clean the contacts with e.g. a wire brush or sand paper to avoid a too high resistance.The resisitance from contact to contact suppose to be 80 Ohm.

If do you need any further translation of the Wiki, don´t hestiate to ask!

Cheers buddy! I couldnt find it, just what I needed, many thanks.

Hi.
I had 10 minutes spare after work today so I removed the fuel level sender.
I tested the resistance as per the data in the Wiki.
I found that all the readings were 130? too much.
I then found a high resistance between the connection terminal and the brass rivet that goes through to the inside of the sender unit.
It was 130? !!
So, tomorrow I will soda blast this area and try and get some solder on without melting the insulation.
Almost fixed.

All repaired.
Working again.
Fixed by a simple blob of solder between the terminal and the rivet.
All good again.
