I see that lots because I off road. The mud or liquid sandpaper
polishes up my belts and they don't grab well when cold.

I test it with a cold off engine and see if I can hand slip the
alternator pulley. If I can hand slip it, it is dead or loose. The
alternator takes several HP to spin up under load and for sure if it
hand slips it won't charge fully if at all.
