So I just installed HID lights and and Edge Juice w/ Attitude tuner about a week ago. I drove to the airport for a weekend trip and upon returning my truck battery was completely dead. It sat for 3-1/2 days. Could either the bulbs or Tuner be draining my battery? Has anyone els run across this problem?

 

the only real way is do do a parasitic drain test and start pullin fuses and unplugging those things you just put on

 

If the edge was installed incorrectly, meaning if the wire that was suppose to go to a switched power source was connected to a constant power source then it would stay on when the ignition was turned off therefore causing the batteries to go dead.

The same on the HIDs. If you installed the relay harness and it wasnt installed properly the relays could stay activated and cause enough current draw to kill the battery.

All it takes is one wire in the wrong spot. It happens to everyone at one point in time.
