Battery is being drained due to a draw. Have to disconnect the alternator and the controller mounted inside the battery box to remove the voltage draw of 9 volts. Must disconnect both, either one hooked up and the draw is still there. Has anyone had this problem before? What does the controller in the battery box do? Are we missing something in the harness that could cause this problem. We have gone step by step disconnecting everything from the key switch, all the fuses and relays. Customer has been jump starting machine due to dead battery. Thanks for all the help.
