I've got a Tipo 1.4 DGT '89
Without any explainable reason the tachymeter switch from Kmph to mph. I'm italian, then that is a problem.
Does someone help me to resolve the problem?

Is there a button to choose mph/Kmph?Maybe a false contact is causing the odd problem.


<--Can my face look like this if I meet a Danish and/or a Swedish supporter!?

i used to have the opposite problem when i had my DGT many years ago, it also used to go very dark for a couple of minutes, then wake up again!

i think the DGT dashboards were fraut with little glitches....

reply to Enzo: there isn't any button, neither on front nor on back of dashboard. I agree with a false contact but the question are the follows:
is possible to solve the problem by a simple switch or a PLC (programmable logic controller) is required?
is the problem on dashboard or is located in another place of driver's cabin?

Vito,

At the back of the digital dashboard should be a jumper on the PCB. With this jumper jou can select whether you want Mph or Kph. This should be a small wire soldered on the circuit board. The wire short-circuit two islands on the circuit-board, or not if removed. Maybe this wire is inside the dashboard, so then you have to take the dashboard apart. Anyway, anywhere this wire should be found, at the best of my knowledge the wire is marked as well. Possibly this wire doesn't make well contact, and so the dashboard changes from Mph to Kph ??

if battery is disconnected or goes flat digi dash reverts to default kph.

Strange - my '89 Tipo DGT did have a switch to select miles or kilometres - a pushbutton switch (and so quite possible for it to fill with dust/jam etc.) (no I don't mean fill with jam, oh you know what I mean)

I am certain of this because I remember setting it to miles to see if I could break the magic ton - I couldn't. It was the 1.6 model, and it was disappointingly slower than my Uno 60!
