HELP, what is make this happen!!

After the WTS light goes out the alternator (voltage, what ever you call it) gauge seems to jump back and forth for about a minute or so. All the lights dim with the gauge down and back up when the gauge is up (low to high). This leads me to think the gauge is working correctly. It will do this when the truck is cold or hot it seems to have not difference.

Heh...that's normal, that's your glow plugs cycling through the "afterglow" cycle to help keep the engine running when it's cold.
