Humming sound when off
I haven't had much time to post on here, but in the last few days I've noticed there's a slight humming sound from the car when it is off. The key is out of the ignition, but it sounds like there's still a very quiet electrical hum from the engine compartment. It's puzzling and I'm afraid it's going to discharge my battery so at home I've been hooking it to a trickle charger at all times.

Have you listened to it for 5 or 10 mins to see if it stops? If it does, it'll be any of the previous suggestions. You could also not hook up your trickle charger, let the car sit over night (10-16 hours) see if your battery is ok. If she starts fine, you know it's nothing to wrry about
