Question about 2003 Harley Davidson FLHTC Electra Glide Classic
I would suggest the fault is probably with the REAR LEFT fitting.
The Front Left doesn't flash because the Rear Left doesn't light up at all - this means there is a lower power drain in the circuit than the normal level at which the flasher activates.
Most likely it is a bad earth.
One side of the bulb should be connected to the positive side of the circuit which runs from the +ve battery terminal, through the turn signal switch and the flasher unit and under normal circumstances would pulse 12 volts DC, turning the light ON/OFF, exactly as the Right Rear signal does. This side will be WIRES all the way to the bulb. It could be a broken one or a bad connection but is the least likely of the 2 possibilities in my experience. You can check this with a multimeter if you have access to one.
The other side of the bulb is the negative side of the circuit and will connect to the -ve side of the battery. Usually this involves using the frame of the motorcycle as part of the circuit and is where a poor connection is most likely to be found.
A visual inspection might reveal the problem - broken wire, loose screw or most likely a rusty or corroded terminal or Earth bonding point or similar. You can always compare it with the right-hand side if in doubt.
Hope this helps
