[TR] TR3 Turn Signal woes

Take a look at current Moss Tube vid on LED bulbs and flashers, perhaps you will find that you need to re-route you grounds so they don't reach the opposite side thru the bulbs.  May need a ballast to interrupt.

Since the front and rear lights work off the same wire and the fronts work I would look at the ground connections at the rear, specifically the right rear.  The wire may be inserted in the right place but is it making connection?  Corrosion or a broken wire may be creating unintended current paths leading to bizarre results such as this.

When the RR lamp flashes is it as bright as the LR when it flashes alone?  Is the LR brighter when you engage the left turn signal as when you engage the right turn signal?

See attached diagram.
When I operate left turn on control head, front and rear operate as they should.
When I operate right turn on control, right front works but both lamps flash in the rear.
Any ideas where the problem is?  I am at a complete loss.  I would think that if I have right/left crossover, both lamps in the rear would flash regardless of which indicator is used.  I checked connections at the rear lamps and only a single line (correct one GR or GW) is connected.  Only line going to right front is GW.  I have tried different connections at left front since the GN and GR look so similar but nothing works then.  I checked all four corners and live/ground wires are going to the correct terminals.
Any ideas appreciated.  Thanks
