Hi there,

You may have an intermittent problem with the alternator, have it checked with the light on you may have sticky brushes, have this simple tested done first.

Hi there,

If the alternator is working as it should, and the voltage reg is OK, the problem will be in the loom or the circuit board of the instrument cluster, this will be a job for an auto electrician to hunt down.
