Alternator?
 

Have a bad alternator, ordered a new one. New one is a Mando style 65amp. Pulled the old one out and there a bit different. Am I good? Red to red, purple to purple, bat. to bat. and the last wire to E on the new alt? There is an L2 and a P on the Mando also they have plastic caps.https://cimg1.ibsrv.net/gimg/www.off...f41e85e702.jpg
