I've noticed over the last few years that my voltage gauge always reads higher with colder weather versus summer and wondered why.
Does the regulator in the alternator (or PCM if applicable) compensate for colder temps and increase the voltage? Or is it just a matter of colder wires having more resistance?
Just curious.
Thanks. Joe.
