Ok here's the deal; I have my wagon wich im putting a new system on, my factory alternator with the Big 3 upgrade was hiting 14.1 volts. But with the lights on and the system bumping the lights go low. So i decide to upgrade and bought a 165amp high power alternator and 2 extra bateries.
I just installed the bateries with 0 gauge and the new alternator, and when i crank the car on its hiting only 12.0 volts. Why? What im doing wrong? I dont get it
. I can change the alternator if that its the problem cause it has warranty.
Can anyone give me an advise on this issue? Thanks in advance
