Polar 720 - broken wires

Hi, kind people!

I have wires broken on the connector of Power Output Sensor. There are three
colour-coded wires, blue, red, green.

The connector looks like this (from the soldering side)

If you take the bandlebar mount apart, you'll find the wires soldered
to the socket have the same colours and match those at the plug.

If you are brave and take the power unit at the chainstay apart, the
wires connect to a header and are in the same Blue, Red, Green order
looking from above into the back of the plug that connects to the
header.

FWIW, Blue is ground, green is +3V and red is signal.

Note that the plug has THREE parts which screw into each other. There
is the plug itself with the pins, a sleeve with the stress relief
fingers and a cap which compresses the stress relief fingers. Be very
careful that screwing the sleeve or the cap on doesn't twist the wires
and cause the same problem all over again...

Thanks, Orin.
Your comments are much more useful than all useless support stuff at
