Fiat Punto Grande (56) Battery Drain Problem


Been having ongoing problems with my 2006 1.9 Punto Grande 130, the latest of which is the battery occasionally draining over night.

A while back I noticed that there was a over-excited relay one night and the next morning my battery was down to the 10/11v mark. I swapped the battery for a fully charged one and everything seemed fine for a few weeks. Now exactly the same thing has happened again.

I checked the 5 big cube relays for operation and continuity and they all performed perfectly. Changed battery again (12.7v charged - 14.0v whilst running). A draw test showed 35mA so there's no major draw. I was happy there wasn't an issue and it was just one of those things, being winter and lack of a long run.

Started her up to let her idle for 15 minutes which was problem free, but once I turned off a relay started clicking intermittently (which I couldn't pin point) and the throttle body would operate causing the plate to open and close intermittently.

As of now I'm a bit stumped, any advice would be greatly received!

Many thanks,
