Battery light on at higher revs?

Hey guys. My 1991 1.9D (1Y engine) battery light is flickering on and off (though more on than off) when the engine is at higher revs. My voltmeter reads a steady 13.8v but this drops to 13.1v when at higher revs. Could this be the voltage regulator? Hoping so but wanted to seek some advice before throwing any money at it. Many thanks as always for all your help!

I'd say so, but I'm no expert

Almost certainly worn brushes on the regulator. It can be changed easily and cheaply without removing the alternator.

Reads to me like the Diode plate is on the way out.
you have a limited time to fix it.
Mine flickered at high revs for about three months
Any local Alternator/starter repair shop will do this and very cheaply.
it cost £27 to fix mine
which ever it is your battery will thank you for a quick fix
