Dear All
I've been having some battery problems of late and without a battery tester, im wondeirng whether my alternator isnt kicking out enough

With the engine running it produces 13.89v but what confuses me is that it does not rise even a tiny bit when the engine is revved to 2000 rpm

Is this normal? Does the voltage regulator really stabilize it that much?

If so, gues that points to a poor battery


thanks
