I have just remedied a non functioning St1300 power screen
Symptoms: wouldn't go down but would go up........turned out to be the lower limit micro-switch
Part number of the original switch is ABJ29084 Matsushita
Replacement part is a Panasonic ABJ261460, which can be obtained from RS components for £7. The switch is identical in every way but comes with three wires
Cut the white wire off (normally open) and voila you have the red and black wire to solder and your done
Hope this helps peeps out, safe riding
