Schematic courtesy of a previous post by....... melbXS........ Brian.
Continuity is one test..........but it s the resistance scale and test that will show up bad coils  or faulty connections on connector blocks or  joins.
Set your meter to Ohms and  on a suitable scale.......... if it s not an Autoranging Digital Multimeter.
Pull the 4 terminal connector off the TCI Unit and test there.
Test between the top terminals Y/R AND Y/G...you should get 670 ohms to 720 ohms or .67 K to .72 K depending on what scale you are using .
Approximately the same readings should be obtained between the remaining bottom two wires ...W/R AND W/G.
If you don t get any reasonable readings then use the continuity test between the connectors and coil on the same colour wire between different points to see if there is a broken wire / dirty or loose terminal connection or a break or bad solder joint depending on how it was repaired.

testing pick up coils

Q for the electrical minded
My project bike has the old rejoined and taped repair done  to the pick up coil wires down near the vac advance.
It's going to be a while before it gets a battery or an attempt is made to fire it up but would like to know in advance if the connection is good
So I have this multi meter that I'm not qualified to use but do know how to set it so it makes a beep when testing continuity of a wire. ( not bad for a nut spinner and spanner twirler)  8) and was wondering where to put the two leads on the meter to test pick up coil wire continuity.
Explanation in wire colours would be appreciated for the mechanically (not electrically)trained.
