I'm in my 82 diesel at a camground and after having a tough time starting
this morning, it suddenly refused to turn over. It seemed like the battery
still had juice, so I suspected the ignition switch. I just tested jumping
the big red wire to the red wire with black stripe on the ignition pigtail
and it turns over.

So I have a new ignition switch sitting at home. Perfect right? Is there
any wisdom on making my broken one work enough to start? Or is it possible
to actually hotwire it? My situation is made more complex as I need the
glow plugs warm as well.

Thanks for any advise!
