Tools is correct:  the front turn signal bulb's wire is crossed somewhere.  The front and rear turn signals are normally wired in parallel to each other, which gives both bulbs a full 12 Volts.  If you are reading only 8 Volts, then it is wired wrong.  The fact that the headlight is flashing when you activate the left signal light, indicates the two are connected in some way.  By disconnecting the front light, and seeing that the rear light works, you have located the fault:  the wiring on the front left turn signal, and the headlight circuits.  Excellent trouble-shooting, Tex!  Now you only need trace those wires, in the organized mess that is your wiring harness.  Unfortunately, this is going to be a taxing job.  Still, you know which wires to look for, and it is a relatively short trail to follow.

Look up the color code for the headlight Hi/Lo wires:  try to determine which circuit on the headlight is cross-connected, by switching between Hi/Lo modes.  If it flashes in both modes of the headlight, then it is most likely the ground side is cross-connected -- not gospel, but most likely.  If it only flashes in Hi, or Lo mode, then follow the wires for that circuit, only (check the schematic, as they will be different color-coded wires).  Good luck!  Let us know what you find.  Cheers!
