Hi all, today my Skoda Fabia 1.2 started to shake and it stoped when i was driving it and the light from batterie is on. What can be? On internet i saw that it can be the alternator.

Yes, you need to test the alternator output.

The funny thing is that i tried to stat the engine now and everything is ok. I realy don't know what to think.

I will get someone to check the battery the alternator 

Maybe the battery to chassis earth.

I checked today the battery and the alternator and are ok. I hope it wont happen again. Thanks for advices. I'll come back with more comments if i will find the cause

Can anyone to explayn me what these means?
