TK, if I'm reading the instruction booklet for your tester correctly, you can't use it the way you are trying to. If you look on the 2nd page where the chart of the LED's behavior is shown, you should get the following:
1. With the red test lead on a + DC wire and the black test lead on chassis ground, the tester will be seeing 12V DC + and the LED's will show up as given in the 4th line of the chart, meaning neon off, Left LED On (the one labelled + DC), right LED off, no movement on scale.
2. With the red test lead on a - DC wire and the black test lead on chassis ground, you'll be measuring continuity (both are at the same potential), and the LED's will show up as given in the 1st line of the chart, which just happens to be the same as condition 1.
The only way to use the tester for what you're intending is to separate the two wires you wish to hook the inverter up to, put a test lead on each, and your tester LED's will behave as shown on line 4 with the LED lit depending on whether the red wire is on + or -.
