Mc2505 help needed

[roccale]

Hi, I just bought a mc2505, is very good, only drawback is a w-meter that does not work.
Does anyone have any tips to solve the problem.
What is wrong is right.
I measured with the tester and the resistance of that property is by far superior to that of the good.
Besides that my 2505 has an internal wiring and arrangement of the components that I have never seen in the photos that can circulate in the network.
Its serial number is 18k24.
Does anyone know what year it can be.
If I can add a photo.
Thanks to all.

On mine the problem was due to dirty contacts in the meter range switch.

I've had the same problem with mine.

But it is possible that a single w-meter does not work because the switch?
I had a look and w-meter are in parallel, to work left, to right no ...
I hope it is the switch, but I have my doubts ....

I've cleaned and lubrified the switch, nothing to do...
What can be?
some resistance? But what, I do not understand.
