Hi all,
Was fitting my new samco hoses to my car last night (coolant) after fitting them and filling the system back up I noticed there was quiet a loud sort of ticking noise coming from the alternator area, I had left my car interior light on and stereo for about 2 hours whilst working on the car (not normally a problem) It still started first time and didnt struggle or anything but just this noticable noise

Would this be the alt on it's way out? or something else?
Cheers for your help
Adam.
