Hi guys and girls,

Recently replaced my alternator on my 90 300D with a rebuild. Everything is working fine, except I notice that my lights (headlights, dashboard, interior lights) pulse or flicker. Happens more when I give the car gas. They go bright and then dim. Everything seems to be working fine otherwise. Can this be a bad rebuilt alternator? I bought it from a local auto parts warehouse. All help is greatly appreciated. Thanks
