Replace the Alternator.\015\012Sounds like the internal brushes have worn out as you appear to have the correct feeds to it.\015\012If you are tempted to open the alt to have a look at the brushes, be careful as incorrect assembly can cause serious damage as can incorrect re-assembly. You can simply replace the brushes but I would advise against it as the copper rings the brushes rub on (the slip rings) will also be worn and require replacement, this is difficult if you do not have the experience. Also, the bearings should also be replaced as they will no doubt be worn too. Altogether a specialist job, so grab yourself an new or exchange alternator. if you have to get a second hand unit, have it tested BEFORE you fit it..
