wire size for high amp alternator

ground to the trunk???


there is a chart....i'd have to dig it up, but it indicates recommended charge wire size for alternator amperage.

if you have a pretty stock electrical setup, i'd go with 8-gauge minimum....i have an aftemarket ignition setup, and use 8.....if you have a high-power stereo, i'd use 1-2 gauges higher.

if you don't have a lot of current-drawing modifications, your alternator's 130-amp capacity will never be reached anyway.

you can only charge the battery so much.


the BEST thing to do would be to figure up your car's maximum current requirement (driving at night in the rain with the stereo cranked)
and use that for your car's used current.....gauge the charge wire from there.
