battery light

Post by picassodad »

The lads xsara picasso 03 plate 1.8 dohc petrol did 41.7 miles per gallon real life over 300 miles on saturday with all sorts of driving.

Anyways the reason for this thread, occasional appearance of the battery light, It seem to start all ok with the engine whizzed over reasonably fast the times I have been in it.

We did a quick check for bad battery connection when we first got the car, all seeming ok.

During our run this weekend after about 50 miles or so the battery warning light just came on. We pulled in and he switched the car off. After say a minute, he started the car and all was ok.

On the way back again after about 60 miles or so, the battery light cam on briefly then went out all buy its self.

Any ideas, is this a common fault?

I am aware of the bad connection/melting connection/overheating connection problems with these cars.

All help and suggestions welcomed.

It still needs a good service in about 1k miles time, done about 2 k miles in it so far.

He has said that the car has done this, the battery light, before.

The car does seem to mist up indise a bit when warm so there may be water under the carpets, we have not checked yet. The stereo he has fitted has a voltage indicator, was 13.4 volts after the first red ligh appearance this week end and did seem a bit on the low side on the way home, in the dark, Headlight seem bright enough.

That usually indicates a battery charging issue - so I think you need to get your multimeter out and check the battery voltage at rest and then with the engine charging to see what it reads then. The 2 obvious suggestions are either the battery is past end of life and not holding its charge or the alternator is not outputting enough to charge it.

This is the time of year when it's colder that these issues are more prevalent when there is more demand on the battery. It may even be the accessories belt is slipping - have you taken that off recently?

I'd say the battery is near it's end. The 2003 Picasso I've currently got was doing the same thing. New battery solved it.

The lad uses the picasso for the commute to work but has some time off this month. When i have it again i will check over battery, earths and alternator output, as well as fuel filter and spark plugs. Will also make a cover for the drive belts, maybe the odd spash of water soaked the belt form time to time, but no squeeeeel heard.

I'm having exactly the same issue with my Berlingo - intermittent battery warning lights.

Everything seems to check out - 14.5v when running (with the battery light on or off) and 12.5v when off. I've swapped the alternator, and the battery is less than 2 years old.

Next steps are to check the earths, and make sure the output cable from the alternator hasn't got damaged.
