1. Remove the existing loop wires and connection box plus the coax cable. If the coax
cable was put into a duct, use the old coax cable to pull the new coax plus 12V power
cable through.
2. Put the wires of the activated detection loop in the slots, with the termination box in
the spot where the 470 Ohm resistor used to be and cut the excess length of the
wires. Make sure karts can not pass outside the detection loop. Extend the detection
loop outside the track if necessary.
3. Put a heat shrinkage sleeve over each detection loop wire end and strip both wire
ends. The Soldering necessary is best done with help of a propane fired soldering
iron. Solder both loop wires each to one of the two yellow wires from the new (larger)
connection box now housing the connection box plus the electronics producing the
beacon signal. Slip the shrink sleeves over the solder joints and hold them over a
heat source. Please make sure insulation is perfect, in order to have best
performance over a very long period of time.
4. Fill the slot with silicon. Make sure the silicon is fully under the surface of the track,
otherwise the tires may pullout the silicone.
5. The detection loop is sensitive to interference, possibly emitted by nearby cables.
When possible keep all cables 5 m 115 ft away. Also make sure karts on other parts
