This is the front panel of your ELIXIR ELX-30 30AMP Converter/Power distribution panel
I am assuming you have pulled the four fuses in the UPPER RIGHT HAND SIDE of this panel and found that one fuse disrupted your .4AMP current drain.
These FOUR FUSEs are your 12VDC POWER DISTRIBUTION PANEL with FUSE 1-3 being for 12VDC LOAD CIRCUITS 1-3 (Left to Right).. The fourth FUSE will be a large FUSE VALUE and is your REVERSE POLARITY FUSE.
Coming out of the back of the ELX-30 you will find several COLOR wires that will go to a group of wiring using wire nuts. These are all of your 12VDC Appliance wiring divided up into three groups. I refer to this as a RATS NEST of wiring...
BLUE WIRE goes to 12VDc CIRCUIT #1
BROWN WIRE goes to 12VDC Circuit #2
YELLOW WIRE goes to 12VDC Circuit #3
RED WIRE goes to your POSITIVE BATTERY TERMINAL
WHITE WIRE goes to NEGATIVE BATTERY TERMINAL and FRAME GROUND
If you have pulled on the CIRCUIT FUSES for CKT 1, 2, or 3 then you have a drain coming from on the those three circuits. It is most likely the CO DETECTOR. These fuse control your DC Appliances which are both fed by the ELX-30 converter and your 12VDC Battery.
Without being connected to shore power the ELX-30 Converter will not be producing 13.6VDC - Only the connected 12VDC Battery will be provide power to the connected appliances in this mode.
To check if the converter is operating normal pick up a multimeter and measure the charged up battery DC Voltage at the battery terminals. It should read 12.6VDC. When you apply shore power to the trailer the Converter will provide 13.6VDC across the 12V battery terminals indicating the converter is operating normal...
Let us know which fuse you pulled to kill the .4AMPS DC load.
