Alternator belt tension 2014 Norge.

[Westie]

I don’y have the specialist tool to set the alternator belt tension on my 2014 Norge, in the past on old cars I used a spring balance, has anyone ever done this and how much movement and pull on the spring balance did you use?
Maybe you have a better way?
Thanks

I’ve replaced several alternator belts on our 113,500-mile 2005 Breva 1100. The belt is correctly tensioned when you can twist the new belt 90 degrees at the mid point between pulleys. I’ve had no issues using this method.
