Hi all, I have a 93 sc hiace 2.8 diesel auto. Just recently I had the alternator changed, now when i start the engine the 4 or 5 lights on the dash come on the battery is charging but seems eratic. After about ten minutes the lights go out the alarm sounds and every thing is back to normal, I went on approx ten mile journey every things seems ok. Any ideas what the lights and alarm are about?
