Hourmeter on 5245

[tagew]

Hello, I have a friend who have problem with the hourmeter on his 5245 from year 1988. The tachometer is working but not the hourmeter. He has also changed the whole instrument but the result was the same???
Does anyone know anything about this problem or know where to find a good electrical diagram for this model?
