[hpinitromt]

i bought a power supply that came with no instructions..on the side is a power grid with screws, 6 for output marked + and - and then there is 3 screws for input, but there not marked positive or negative, one is marked by the letters FG, the second is, N and the third is L, i have a 2 wire power cord to plug into the wall but, what do the letters mean? which is positive and which is negative? ive seen anything marked FG,N and L, darn chinese, lol
anyone know?

Throw up some pict's of this. More than likely it has to do with different voltages.

i was just teasing, don't get bent out of shape...i was planning on posting a pic, just didnt have time yet
you can switch it between 110 and 220v, so i figuring thats causing the confusion
i bought it at kershaw designs, ive bought many things from him and never had any issues, if you email him, he gets back to you in an hour or two, but for some reason its been two days and no reply, very unusual for him
i post a pic tommorow and maybe it will help you understand
