That only shows the battery cannot deliver high current without droping below the "bad" level voltage. Either because it's actualy bad OR because it wasn't fully charged.

You need to perform the other measurements before ruling out anything !

Unfortunately Stace, this doesn't prove much beyond the fact that the battery reads 8 volts when tested with a voltmeter. Bernie's procedure, as he's posted above, should give you a more definite result upon which you can then decide a way forward (ie as to whether it is the battery or alternator or poor - high resistance - connection somewhere or maybe something more obscure)

Re: Fiat grande punto 2008 1.4 Battery / alternator / Power steering problem

Do you have breakdown cover? They can often come to you and test your battery/alternator if you are stuck on your driveway. But if you can get a jump start, then as suggested, head to your nearest Halfords / F1 Autocentre / Kwikfit, who all offer free battery testing. Your local car parts supplier or garage might offer the same too.

I was having trouble starting, I swapped the battery and it didn't help and it turned out to be a bad connection (very worn earth cable). So it's worth getting a full diagnosis before spending any money and swapping parts unnecessarily. If you have some tools, you can check your earth points yourself: https://www.fiatforum.com/grande-pun...ng-points.html

P.S. You can take the battery out of the car and take it to Halfords if you can't get there with the car. But the downside is then they can't check your alternator

Looks like alternator issue, because after driving on highway battery had 8V. So it looks to me that alternator wasnt charging and car runs only from battery power and drained it to 8V. BUT - How old is that battery please? If it's less than 4 years old, it also points more to alternator. But if it's 5+ years old, battery can be dead itself and is unable to charge itself (and they altermator is 99% OK).

And power steering & ABS - they are sensitive to correct voltage, so don't worry about it at this time ;-)

Re: Fiat grande punto 2008 1.4 Battery / alternator / Power steering problem

Hi!
I was just about to write the same.
I have been in exactly the same situation, but my engine could still be restarted but not started the next day, I removed the battery (public parking lot) and carried it up to my first floor apartment and connected my home charger to it, the next day the engine could be started but when I gave the slightest gas, the battery light lit up and there was no power steering.
I got a really good offer from AutoDoc, approx. 750dkr ~ 85GBp, but their inventory management had obviously made a mistake, what should have been a refurbished alternator turned out to be a brand new original Denso / Marelli 105A Made in Italy in an unoriginal box.
I still use the Varta battery that was in the car when I bought it in October '17 I do not know how old it is, but the car starts the first time even if it has been parked 1.5 weeks and it is -5C outside.
BRs. Kjeld.

Re: Fiat grande punto 2008 1.4 Battery / alternator / Power steering problem

Starting and charging paths should be considered as a whole, ANY bad connection/cable WILL end-up with issues. It is not as simple as "install a new battery ans you're good to go" or "replace the alternator and you're good to go" ! You definitely HAVE TO find where the issue is ...

Re: Fiat grande punto 2008 1.4 Battery / alternator / Power steering problem

You're right Bernie, hence my use of a home charger (Hint, hint!), I had already checked all the connections when I changed the clutch last year (it's much easier when the gearbox and battery are out of the way).

Battery light @ dashboard is the obvious indication of a charging issue. I wish you had inspected the dead alternator; you'd probably found the brushes were seized or worn, not allowing a good contact with the inducting coil's collect rings: no (less) induction = no (less) power output = battery not/dis charging.

What do you thing they do when refurbishing alternators ? New regulator/brush holder, new bearings, rings cleaning (machining), that's all !!

BRs, Bernie

Re: Fiat grande punto 2008 1.4 Battery / alternator / Power steering problem

No Bernie, I still got it, it is in my dad's garage, I actually tried to change the regulator while I was lying under the car, but I gave up, there was not much room and one of the screws had grown tight and was very soft so even a whole new bit under pressure resulted in a tapered hole and there was no room for any of the drills I had access to, but it didn't matter much because the light metal casing was cracked in several places (standard error!) and I had got the new one in the same delivery, (I could have returned it if the operation had succeeded). So I have a spare regulator, but we have two other Puntos in the familly, you never know.

Re: Fiat grande punto 2008 1.4 Battery / alternator / Power steering problem

Thanks for all the input guys, I've ruled out the battery by hoping for the best and buying a brand new one. Car ran like a dream for an hour, pulled up on my street, power steering went, abs light came on and wouldn't start. :'( so either alternator or cable problem I guess. I found a friend who has a full diagnostic kit so hopefully that will work? I'm in Leicester btw

I have been lucky in a way that my car failed to start both times once I actually got it home

Re: Fiat grande punto 2008 1.4 Battery / alternator / Power steering problem

BTW I never had battery light on the dash only abs, power steering in that order. If I can start it in the morning I'll take it Halfords

Diagnostic kit found no fault codes. Can't start the car long enough to get it to Halfords all multimeter readings seem normal. Cleaning grounds next

Have you taken the battery off to charge it?..These cars do respond to generic fault code readers but prefer Fiat stuff.
