    Solved alternator charge stud extender

    Hey everyone. So I bought a 200 amp alternator but it has the battery cable stud on the back, not the right angle adapter that puts it on top of the alternator. Does anyone know where to get the adapter? It'll make the connection a lot easier when I go to connect a heavy cable to it. Thanks.

    Solved Alternator issues.

    When the Check Charging System light came on on my 2005 Explorer XLT, I changed the alternator. That did not correct it. I changed the battery. No change. I finally figured that maybe I got a bad alternator (from Advance Auto) so I got another one from a Ford Dealer. It was rebuilt but they...

    Has anybody modified their charging system?

    My stock 7750 3G alternator in my 1995 van is rated at 95 amps which is low compared to more modern vehicles which use 130 to 160 amp alternators. I've looked into 350 to 370 amp alternators but they cost almost $500 which is a huge investment in a 25 year old vehicle. The reason why I'm doing...
