Then your draw is in the system somewhere, You just need to continue to disconnect things until you find the problem. Now do you have the ignition switch disconnected? If you have that switch disconnected and you are still getting power to the system we need to find out how it is bypassing the switch. The ignition and headlight switches are the only things that have power before the system and if they are both disconnected then technically there is no connection. With the possible exception of the voltage regulator. If you have the A1 25 amp system then disconnect the plug from the main harness to the regulator on the firewall, if you have the A2 60 amp system then disconnect the #5 wire at the alternator but be sure to wrap tape around it so it does not short out on anything. With all of that stuff disconnected if you still have action at the gauges then you are going to have an internal wiring issue.
