Default tach problem

My tach is below zero after the car is shut down with the key out but when I turn it to ACC it jumps up to zero. Any thoughts ? Any knowledge of the subject would be appreciated. :cheers:

That is normal. Your tach is just responding to voltage. It is just preparing itself for the excitement you are going to provide when you activate the starter.
