Hi..

Need some help. I have got proplem with my Vanden plas 1982 speedo meter.
It don´t operate properly.. When i drive normally, some times speedo dies wholly.. and then it works again.. Usually when i shut the engine and start agin, then it works agin?? I have got 3 years old sensor in gearbox, and drived about 30 000 Kilometers. My speedometer has drived
411 000Kilometers that is lot of miles about 247590 miles..

I´m not sure is there some contact proplem or what?
I have got haynes manual, but i can´t find speedometers wire color and this speedo meter indicator is also lost..
It is easier find the faul if i can measure some voltage somwhere.. But haynes manual is confused..

Can someone help me?
