Boot heaters

Carper/flat cat 5 used to run from the heater to the connector on the cuff.
This is the amount of insulation to remove allowing it to pass through the barrel connector; it is rubberised, but not very compliant. There are exposed cores after the case if screwed on.  Heatshrink required to cover the gap.





Routing on the sole

















Joint on to the heater






6 x 100R 1/2W resistors, carefully soldered onto stranded wire. Solid wire has historically hardened and failed very quickly

















4/12/19 Both 0V wires failed where they pass through each insole. Used a longer piece of stranded wire to solder between 2 resistors in case the solder had wicked and the wire work hardened.
