Its on 3dr cossie, have checked output at battery & its only 13.8 volts but thats with 2 different alternators. Iv'e never had problems with the battery going flat in 2 years, it was just that the light glowed at night on main beam & battery light didn't go out until you reved the engine to 2000rpm , so i thought i better change my alternator before it let me down as i thought it was on the way out. I fitted a brand new one & it was exactly the same, so i suppose it must be a fault on the back of the instrument cluster or wiring but their isn't much wiring really, live cable that goes from the Alternator straight to the battery & the blue wire that goes through to the ignition/dash.
