Problem! I just picked up my Farenheit (thanks leemik), but the power plug on it doesn't have any markings for positive or negative??? both are black, one has text on it (written in red). I assume that is the negative one, but can anyone confirm this?

thank you!

 

Use a resistance meter, place one lead to the chassis (metal) which is ground and the other lead to one of the two wires you are talking about. When the needle pegs you are on the ground or negative wire. The other should be positive. If the text is in red I would think tht would be the positive. Dont forget to use in line fuses.

 

ding! pos. was the one with text. had my video department sort it out for me.

thanks for the tip
