You need to join the center and right hand contacts together
using a small blob of solder between the two as shown in the
illustration above. Be careful not to put too much solder on;
it just needs to make a connection.
Please Note
This should be done with a low voltage continuity
tester such as a multimeter set to the Ohms
impedance range.
This should show as
an open circuit - ie
greater than 100M
ohms resistance.
Check connections will a test meter

This should show as a
short circuit - ie zero
