vectra red light on without key?

Did you replace Altenator with a new one or second hand from breakers yard, i have heard of this before on other cars, if the Altenator is no good it can let the power from battery back through which lights up the dashboard, they have a non return diode built in to stop this and it sounds like that has broken down.
