My felicia ignition is switching on all by itself, even though the key switch is turned completely off.Has anybody any idea as to why this is happening?Twice I've returned to a completely drained battery and am now having to disconnect the battery every time I park the car.

As no-ones replied yet I'll add my guess. I am guessing a fault with the starter solenoid, or a short in the wiring somewhere (perhaps it only shorts out when rain gets in?)

Ignition switch faults are common on the facelift [chrome grille] cars.
