All you need is enough tension to keep the belt from slipping.
THis will depend on the % of belt wrap, if its high (goes almost 1/2 war round the pully ) lowerr tendion is fine.
You are looking to keep slippage low as it causes heat in the pulley , which is passed to the font bearing .
With the batts low start the engine and after 5 or 10 min shoot the temp of the alt , and the pulley.
If the alt is hotter than the pulley , the tension is fine.

*yes, definitively need to be tested under load. if the batts are 100% charged the alternator is not under load and the belt is basically just going around..
its a dedicated alternator belt and covers a good part of the pulley, probably 1/2 way around.
thanks to everyone, i will try some of those methods.
*1/4" deflection down from a straight line*on the long*span*is what will work.* Plain and simple.* Don't forget to tighten after four or five hours of run time.
