no constant

[mushupork5]

this problem comes in and out but I keep losing constant current through my car. The volt gauge shows zero with the car in off or the accessories position and my stereo wont turn on without the car on. Anybody have some suggestions? I have recently changed the alternator (2 weeks ago) so I don't think that is the problem. Thanks

Might be the switch located on the Key, occaisonally after starting it may not return correctly to the ON position.
