Hi,
One person gives me 2 vdo tachographs. They lies in garage about 1 year without power. Tachographs owns batterys are dead(7 and 9V). Now they do not work any more. Is there any change to get them work again?
Thanks!

I allready try to replace batteries, but nothing. I even call to workshop, where they repay thats things, and they told me that there nothing to do. It is not possible to repair those tachographies. But I think that it is possible. Can someone tell me, is there any chance to repair them?

OK - so lets start from the begining, we need to make one.

1) Metal case - metal - oh yes dig a hole out the ground.

2) Plastic case - made using oil - oh yes dig a hole out the ground

3) The paper disc - orr wood - that comes out the ground.

Are you trying to tell us this thing can *NEVER* be made to work - not even
by the maker (Unless they epoxy over the contacts)

Only the producer can awake it but with a serious charge.
