I have recently installed all new electrics, pots and pickups in my left handed telecaster. It is my first time installing and i put in a jerry donahue in the bridge and an aptr-1 in the neck. i had to use tracing paper to turn the schematic the right way for a left hand guitar and then when i finished and plugged it in it didnt work. The only time i get a sound of of the guitar and it plays is when the selector switch is half way between its new selection (out of place) but when it clicks back into a new selection the sound goes back off. N e ideas?
