Good Evening lt2duffer, thanks for the feedback, I did suspect the "multi-Vee" section was worn or damaged. With most of those belts the friction is in the "multi vee" not so much with the tension, it is quite amazing what actually happens when an area on the belt actually wears, the frictional surface-area is lost and they run erratically, I did strongly suspect that was the actual problem, an interesting problem and a good solution.
I have also struck worn drive pulleys from constantly slipping belts, but this was more often with single "V" section.

I don't like running belts excessively tight, they overload component bearings, the serpentine idea is excellent and normally only has a simple idler tensioner.

The early VW beetles had a unique way of adjusting tension, it was with an actual placement of spacers on the generator, the "V" section was actually altered in diameter, I always thought it was an incredibly clever idea, it was the smaller diameter pulley with the most load.

Well done!

Cheers, qldit.
