Cutting out

Having some trouble with my 197, sometimes when i go to push the start button it completely cuts out, lights dont work nothing electrical works! Im taking it back to garage tomorrow but wanted to see anyone on here had any insight into this? thanks
 
Not heard of that one myself but def sounds something electrical. Hopefully the dealers will find something
 
Could be a faulty earth or water ingress into some wires. The Main wires running from the fuse board on the passenger side can rub on the chassis just below the headlight behind the bumper. Worth a look if their computer doesn't show anything amiss
 
So i took it to garage i got it from they had a look and they think its the loose connection to the negative side of the battery so they ordered a new battery in.
 
Didn't think you needed a new battery but if they changing it under warranty then that great. Does sound like a dirty connection
