big 3 question (voltage jump)

[swangin68 10+ year member]

my alt normally charges at 14.4 volts or so and i ran the big 3 with 4/0 cable,, and the cable from alt to batt raised my voltage to 15.2 volts when charging, this seemed to high to me so i unhooked it and just left the big 2 on.. why is this?

No,thats probably true alt voltage output but with the smaller factor cable it lost so much and when you did the big 3 it kept the actual voltage..I bet after it warmed up it would drop to 14.8 or so.. Not to worry,15.2 is not bad at all and shouldnt have any negative affects on your cars electrical system.. Amp should slam though! lol

Yeah, I'd love if mine charged at 15.2.

Hmm I have the same car. Maybe i'll go out and check my voltage to see what mine's at //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

My stock alt charged at 15.1 for about 10mins of driving. Then leveled out to 14.8

Seems perfectly fine to me.
