ok, i opened the watty and turned current limit pots to max (fully clockwise), but this didnt make any difference. also i have 2 servos that power microswitches to the weapon. before i used to use a nicad pack to power these, but now i noticed without this pack their is still power for the servos. i presume they get their power from the watty now? im crap with electrics and i just plugged everything in as per the instructions. and forgot to plug in the nicad pack but realised everything worked without it.
