alternator readings poss faulty?

[Bigdunc]

tested my alternator, got some low readings i been told it should be about 14v readings im getting are

Engine running: 13.78v
Engine Off: 13.10v

guessing alternator is not working properly?

It will be around 14v running and 12v when off. If your not having any issues with you battery I'd just leave it

i just replaced the battery, as old one was on its last legs, are them readings ok or would u look in to poss alternator replacment? i have checked and its under a year old so i can take it back if i need to.

where are you testing this, across the battery terminals? whats the reading direct at the alternator stud?

[Bigdunc]

The readings are from bettery terminals, I tried from alt but for some reason my multimeter didn't pick anything up, gonna get a new multimeter or even one of them battery/alt testers I think.

Just bear in mind, if you remove the +ve from the alternator to test, it won't give an accurate value.

The figures you have stated sound well within normal limits.

It might be worth asking why you are testing the alternator in the first place?

[Bigdunc]

I first thought it was that as when got car the bettery was jacketed and car always struggled to start, after changing battery still struggling to start, now starting to think starter motor, conections to it look pritty dirty and could prob do with wacking on new ends or cleaning old with wet and dry, been quoted new starter from work for £43 so worst case I'll change it:)

clean up all the terminals to starter motor and make sure all your engine earths are cleaned as well, try these b4 getting a starter motor
