#1: alternator not charging battery Author: geordiejames, Posted: Tue May 27, 2014 2:30 pm ---- My alternator is not charging my battery on my 03 1.1 pug 206, when i checked the alternator there is 13.5v coming out of it at the main cable so i cant understand why its not charging the battery

Really I'd like to see over 14v at idle no load. Get a proper battery test done. I have had a failing battery pass a test but only the one. Also check your earth connections and the live on the alternator isn't corroded.

13.5 volt output just isn't enough to charge the battery satisfactorily.

Yep load it up. And then check it

#6: Re: alternator not charging battery Author: bodieanddoyle, Location: ColchesterPosted: Wed May 28, 2014 1:48 pm ---- Rectifier. Poor contact surfaces. Battery in poor state of health.
#7: Re: alternator not charging battery Author: geordiejames, Posted: Wed May 28, 2014 4:19 pm ---- I charged the battery in the house the other day and it seem to hold charge should i get it checked
#8: Re: alternator not charging battery Author: geordiejames, Posted: Wed May 28, 2014 4:20 pm ---- What is a rectifier?
#9: Re: alternator not charging battery Author: bodieanddoyle, Location: ColchesterPosted: Wed May 28, 2014 4:59 pm ---- I'd get it checked to be safe. Some motor factors will give the battery a digital health check nowadays. Rectifier is on the back of the alternator. Stabilises output voltage and changes ac to dc current. Not generally available separately but mostly the part that fails in an older style alternator.
