308 GTB speedometer
I'm still working on the restoration of my 308 GTB 1979 drysump and I have one more question for you... My speedometer indicate the speed but not counting the kilometers (I'm in Europe), it stays at 85000 km but sometime it come up a little bit, for example, I did recently 1000km in one time and at the end, the meter indicate 8 km more. Is it a problem with the sensor or is it a problem with the speedometer itself, I checked all the cable behind are well and clean connected, the button to clear the trip kilometer are working well too. (the sensor indicate very well the speed and haven't been changed). Please give me your advice if someone did have the same problem (it's only my second Ferrari and the other one was a 330 but already fully restored). There's also, if it could help, when I turn the ignition, all the light (generator and oil) turn on and at the same time the hand of the speedometer make a quick small jump... Thank you very much for your help.
