I just jumped the XJ for the second time in 3 days, replaced the old Alt. (Powermaster Junk) with my old alt. to see if the gauge read any different. It did stay at 14 for start up and during the first 5 mins of running. After checking it, it's down to 10, put a load on it...red line city. Now I un hooked the pos. cable and the interior light got brighter but I had no way of checking the volt gauge. Battery is new, as of June 5th. I'm out of light to check anything but I'm sure it will be dead in the am. Any ideas. I'm going to check the ground cable at the engine an any other wires. I don't have volt meter at home/ its at work. Thanks, Juice
