107 humming noise from front when off

Unread post by Rallying1 »

Battery keeps discharging in a couple of days from full. Noticed when everything off a slight humming noise from front left of centre as you look at engine bay from front like something isnt switching off. Disconnect the battery it stops and does not come back on until car started again. Any ideas folks?

Could it be coming from the alternator regulator? :)
I used to be indecisive, now I'm not so sure!
I used to ride on two wheels, but now I need all four!
