    Need a bit more info assuming your battery-belts-alternator are in good shape: What lights did you hook up? Relays? Did you wire them into the headlight circuit? I use a SPOD clone as a stand-alone system that separates my add-ons from the JK can-bus system. My SPOD clone also provides battery protection (low voltage cut-off) and ez accessory light hookups.

    How many miles are on your Jeep. Could be the alternator, but I doupt it unless you have more than 200000 miles and still have the original alternator. If you replace the alternator I would consider a HD one to handle any increased load youre putting on youjr system. Aggrex's system is nice. Check out RC's set up on the following thread. It is pretty trick.

    the first thing i do is connect a digital v meter to the batt and see what happens. 14v running. steady? or drop with load. if drop,check connections and alt. usually alt / regulator.

    Glad you found the problem. Thought you had a new battery. That would have been my first suggestion.
