If your cable has tinned ends, cut off the tinned part and strip the plastic cover 21 + off about 1/4" from the new end. The reason for doing this is the screw terminals can't properly tighten down on a tinned wire. Remember, 22 + the red wire is (+) and the black wire is (-).</font> 23 + <p><font size="2" face="verdana">For now, make sure the VS=VL jumper is installed, but you may be instructed to remove it later.
