Update.
Quality belt (important).
Properly adjusted.
And all you hear is a slight chirp when cranking it.
Once started you "cannot" make the belt squeal now.
One thing that helped was I hit up eBay for a nice heavy duty alternator pulley. It was even sort of rough where the belt makes contact.
No need for double pulleys/ belts.
Very pleased. Super good charging.
Fans spin faster at idle, lights are brighter at idle, etc...
And I had no issues with any of these items they are just noticeably improved.
For some reason the eb turns over faster too. Fired up quicker as well.
I think some of that "removed" stock wiring was hurting me and I didn't know it.
Anyway,
Very happy.
Highly recommended.
Cheap, powerful upgrade. Well worth your time.
