  I don't have the pdf's but do have jpg photo's. The correct wiring diagram is 3406691 which is the first photo. It is low resolution and a bit blurry but still readable. Second photo is 3401736 and is essentially the same but is high res and clear.

I found the problem. After taking the front off and the drum out I found the start of the problem.  There was a 1/4" buildup of lint and somehow the wires that come off the motor wiring harness some of them arced across and melted some of the wires together.  I have since blown and vacuumed everything out and tried to figure out some of the wiring.  I have a new harness with the red, black, blue, white/red green/yellow, and red.  My questions may seem obvious to some of you but I gather the black goes to black, blue to blue, white/red to white red, and green/yellow is ground, from there I'm lost.  Where do the 2 red wires in positions 1 & 2 go?  I wired everything as I described above and as of right now have the 2 red wires capped off.  Dryer seems to run fine.  Is this correct or what do I need to do? Again thanks for all the help, input and time you've given me.

  The red wires are only used in the electric heat version of this dryer, not the gas heat version. You did fine.

Thanks for all you guys help and tips.  I do have another question, what on earth would have caused all those wires to melt down and arc current?  I guess we're lucky for kenmores safety controls those sparks could have easily caught all that lint on fire and who knows what else from there.  The lint looked pretty black and halfway singed as it was.  Thanks again

   Either a dirty terminal, loose terminal, broken wire strands within the wire insulation, damaged wire insulation exposing the wire strands...etc. These types of things cause resistance and the motor current through resistance causes heat. Heat and time cause the problem to eventually escalate to the point of failure.

I had a Kenmore gas dryer yesterday that wouldn't start due to a blown thermal fuse .  There was no schematic to take a picture of and servicematters doesn't have it.  Coin-op model 110.87407110. Serial number MB2610811, manufactured in 1992.
