Just finished installing a HO alternator, 150amps
Everything is connected as it was before except now there is a 0awg wire connecting the alternator output to the positive battery terminal.
I've also got an extra 4 awg wire connecting my secondary ground terminal to another chassis ground in addition to the stock grounds
Scangauge puts idle voltage at 14.7, when running approx 80 amps of extra power in addition to normal, voltage drops to 12-12.5V at idle and at 3,000 RPM will return to 14.5-14.8V
The battery light is on, looks dimmer than the brake light and seat belt light and looks to almost flicker sometimes
havent taken it for a spin b/c i have nobody to follow me in case it conks out on me today
