Max Lighting before bigger aultinator?

[ExploringNC]

I want to add some off-road lights but I need to know how much wattage the stock aultinator can handle before I need to upgrade. What recommendations do you all have for a new aultinator and the typical price range?

In the FAQs there is this link: http://www.rallylights.com/other/wiring.htm
It will give you a way to guage the amount of amps you are pulling from the alt.
I have 2 130watt & 2 100watt & 2 55watt lights that may all be on when at highway speeds.
As Khoward said, you should be OK if properly installed.
Seems that audio amplefiers are the real alt. amp eaters.
