Alternator trouble

[Jmh474]

I have a xsara Picasso 1.6 16v petrol 56 plate and Iv got a bit of a problem.

I was changing the drive belt tensioner and I managed to knock a spanner across the alternator positive and ground and got a bit of a flash.

So I was taking my son out and on the way there I got a charging fault message and battery warning light come on, and I have a USB charger which shows the car voltage and it's only reading 11.7 volts while driving.

So my question is has the flash damage the alternator or is there a charging circuit fuse that could of blown??

I would go check out the fuses and output direct from the alternator but it's p****** it down out there.

Thanks for any advice.

Highly likely to be a big 80amp fuse that has popped. It may be in the main fuse box or on a separate mount. Google is your friend for it’s location.

IIRC the main high current fuses on these are located on top of the battery. They are bolt in style fuses, not blade fuses.

Just an update Iv sorted the problem, it turned out to be a loose connection on the alternator it's self so God knows how long it's been like that for thanks everyone
