I have a 3.50-inch tft monitor for video assist.
The power line for the monitor has two separate wire on the end, 1 red and 1 black, both with a little copper wire out
I tried to connect the wire directly to the lead-seal 12v battery. red to positive and black to negative.
The screen doesn't seem to turn on. The battery is fully charged.

I figure I may have connected the wrong way.
Anyone knows how to connect a small monitor to 12v? Do i need other cables?

Thanks!
