One or more diodes in the alternator has gone short circuit most likely, allowing volts back through the alternator to the vehicle via the excitation circuit. Replace or re-con the alternator and all will be fine. Badger.

assuming the diodes are all in the regulator/brush pack you can replace just that on an alternator. I just did the one on my car and it cost around £15 from the local bosch specialist. I was impressed - Cost me about £20 for new regulator/brushes and the

2 bearings which compares well with the cost of a full recon replacement.
