Squeeling V belt and CVF alternator

I'm probably wrong but is the belt shown in the picture inside out....never seen one with the segmented section on the outside, those "toothy" bits usually go into the V of the pulley don't they??

I only ask this because your picture looks to show a symptom we are used to seeing here in Europe.
if i run a European segmented v belt measured in (mm cm etc) on US mopar pulleys /water/alt/balancer the width and angle of V of the belt is wrong, the depth of the V of the belt is wrong and the widest outermost width of the belt is wrong.

and so when you tension the belt properly the tautest bit is the smooth side, and the segmented bit is running in the base of the valley of the V and not hard against the sides. SO the action of the engine turning causes the belt to flip inside out.

hence when someone says, lost a belt or slipping belt, this is what i look for. Namely t,he segmented tooth like section of a modern V belt, visible on the outside rather then wedged into the V.

but as i say could be wrong maybe your belt is just like that.

they do slip and make a noise when this happens, because you are running on a belt surface that was never supposed to see the metal of the pulley.

obviously i outlined a specific circumstance where the belt if fitted correctly, its flips and caused a problem.

but if you fit the correct width and V shape belt, inside out, id expect similar.

not saying you have, I have just not had the experience of a belt like the one shown in first post

one last thing
making 55 amps takes more effort than making 35 amps so your alternator will be stiffer to turn over, especially if the pulley is smaller than standard.
they could have used a smaller pulley to achieve an idle speed alternator rpm, that will charge.
is that what they have done here?

a bigger pulley slows alternator down a bit for a given engine rpm, and will make turning it to make 55 amps an easier job for the belt, basically more surface area of pulley in contact with the belt and an and easier gearing ratio between balancer pulley and alternator pulley.
