DB electrical alternator did not work properly rated output [email protected] idle 200+ 1200 rpm. What I got was appx 45 at idle 150 at 2500. well packed and fast shipping and came with an under drive pulley. I had the right belt size and its only the 2-3000th alternator I've put in. My friend works near a starter alty rebuild place I'm trying them next. The guy there informed me about 165/75idle is what that alternator could reach done correctly.I'm getting one made right now. 200 out of a small case made him crack up. REMEMBER TO TEST YOUR ALTERNATOR AT A PART STORE BEFORE YOU INSTALL IT!!!!!!!!!!!!!!!! the right belt is important too.
