    dimming lights with h/o alt big 3 and kinetik battery

    Hey guys im trying to find out why my headlights and dash lights are dimming with a h/o 220amp alt for excessive amperage kinetic 1800 battery up front and Memphis 1/0 for big three. for the equipment I have a jl hd750.1 and an arc ks300.4 really frustrated I spent a lot of money on getting my electrical and car beefed up to eventually go with a bigger setup and this current setup is causing my lights to dim please help with ways to test. I have clamped it and with a/c on headlights and system up it reads that im only pulling around 70-80 amps from the alternator????

    What brand is your alternator? It will only supply as much power as the system requires, it's not putting out a constant 220 amps.

    its excessive amperage but the alt should be drawing more then 70-80 amps and dash lights are dimming as well even at high rpms

    Get Hids (they are either on or off) no dimming.

    Check the grounds again.

    Re: dimming lights with h/o alt big 3 and kinetik battery

    I agree to the idea of running HIDs, I was runing 2k rms on a stock 80 amp alternator with only the big 3 done and i never had any dimming because i have HIDs. they are only 30-70 dollars now so its not too bad.
