Madjax Alpha body light kit fuse keeps blowing

[Carts4you]

We have installed a new alpha body basic light kit and every time we turn the switch on the fuse blows. We have replaced the lights (front and rear) for another set and checked all connections and plugs. They are all clean. We have our 12v+ coming from the voltage regulator which is hooked to the battery positive and negative (we have a Roypow lithium pack). The only connections to the voltage regulator 12v+ is the light harness and a bluetooth amp. The ground for the light kit we have it from the black bullet plug coming from the car. We have measured the 12v+ and is working. The amp and sound system is working properly, but when the lights are turned on, it blows the light harness fuse. Anyone have an idea what it may be?
