Hummer dealer figures it out....this is a wierd one.

If something like this happens to you here is what you do.

Disconnect the negative and the positive on the battery.  Then touch the cables together for 5 seconds and let them rest for 5 minutes.  After the 5 minutes connect the positive and then the negative.  Problem solved.

Have no idea what this does but supposedly if you disconnect the battery sooner than 15 minutes of shutting off the H3 off, then the "computer" doesn't have time to shut down properly.  Just like your home computer if you just press the power button to shut it off.  After 15 minutes the computer shuts down properly and there will be no problems then.  However I disconnected the battery too soon and the computer didn't have time to shut down properly causing electrical problems.  Hopefully this will help someone along the line.
