Yep, had the same problem when I was putting LEDs in.
Don't use a test light to check the connections. A lot of RVs don't follow the standard electrical code.
On mine, + was black, and negative was white (crazy stuff).
On a standard voltmeter, the red lead is the positive, and the black lead is the negative, when plugged into the correct red and black terminals on the voltmeter (check that too !).
The red wire when connected to the positive, and the black wire when connected to the negative should give you a positive 12ish volts (depending on the battery charge).
If it is negative voltage (little - minus sign is displayed) , then you have the red wire connected to the negative, and the black wire connected to the positive. That's how you know on a voltmeter. Test lights don't tell you that.
Hope this helps !
