MG TD TF 1500 - Generator Output

Greetings to all:
I've been offline for a few months, but I'm BAAAACCCKKKK! I drove my TF home from a parking lot car show after dark last night, which required the use of my headlamps for the first time (after a year of ownership!). I noticed right away that the lights were dimmer than I anticipated and that the ignition light increased in intensity with the increase in RPMs. By the time I arrived home (about a 15 minute drive), the battery was so low that it would not turn the engine over after shutdown. I connected my BatteryMinder to it overnight and this morning, the battery was back to full strength. I cranked the engine, turned on the headlamps and they were as bright as one would expect during daylight hours. The ignition light flickered at idle (normal, I think) and went off when RPMs were increased, as one would expect. So, does anyone have comments or suggestions that would shed light (pardon the pun) on this situation?
Cheers,
Frank

Frank - Run the test described in the Testing A Dynamo/Generator in the Other Tech Articles section of my Homepage at: http://homepages.donobi.net/sufuelpumps/ If the test fails, you have a generator. If it passes you need to have someone look at your regulator. Jerry Felper felperg@earthlink.net or 714-630-1074 is one person who can repair/adjust the regulator.

Does your amp meter show charging / discharging? Should be quite obvious from the reading if the battery gets charged or not as a quick first check.

If it gets discharged with lights on and engine over 2000 rpm, then something is wrong
