    Hello,

    I'm in the process of repairing my Digital Dash and have found the defective part. The part in question is a Zener Diode, and unfortually the only markings it has is 18 and under that 2. Does anyone know what type of Zener this is.

    THanks

    I don't know. I suggest you draw out that part of the circuit and deduce what value it should be.

    If you need help, post the circuit and we can help.

    It's just a pure guess, but is the zener a fairly large one? - it could well be an 18V 2W zener, to help keep nasty big spikes out. If this is the case, it should be directly across the incoming 12V supply - probably after various filtering components.
