160A Alternator Normal Operating Voltage

[domoarigato]

Hey guys!

Glad we have a new section here

Quick question... on 07-14 PPV's what should the voltage gauge be reading during normal operation? Mine seems to always be over 14V but never out of the gauges range.

I understand all vehicles in this year range have a variable voltage charging system. If I recall correctly the PPVs and SSVs came with a higher output alternator correct?

Thanks!

Higher output yes , should keep same voltage ,
What I like to do, give jump to semi truck and watch voltage

Mine is always 12v-14v and I'm running 3 tablets, 2 phones, 22" TV, massage chair, tons of lighting, and a train horn.
