Default Alternator belt tension

I tightened the belt. I could make it even tighter if I knew how much the desired/suggested max tension is. At this stage I can still bend the belt slightly or push it down half an inch. It could be tighter but I was not sure about specifications. The slipping ended so there`s no belt noise any more but voltage still drops down immediately to 10-11 Volts right after I switch things on such as heating, fogs, headlights, etc, especially if I combine these... I will check on the battery but I guess it is not malfunctioning yet. I do remember though that my voltage gauge showed around 15-16V all times throughout thousands of miles. Also, my newish loose alternator belt issue might be somehow related to my power steering pump minor leaking and/or that belt`s abnormal running angle (misaligned a bit). I have a post about that too. I can`t think too much about this car or anything right now these days but will be on it very soon, hopefully.
