First, I would recommend you take the alt. to a shop that can bench test it for you. This eliminates any possibility the fault is in the on-board wiring. If you settle for a test with it on the motor, make sure they connect right to the alt. Some of these auto-parts stores don't and then try and sell you a new alt when all you needed was a cable. Don't fall into the trap of buying a cheap reman and turning in your stock Denso for core. Try and fix it yourself or get someone to repair it. The after-market and remans probably won't last as long as a repaired Denso.
