<VV> 66 Monza Sedan electrical short

[Carl Wager]

This 66 was recently restored.  It was completed about 15 months ago.  Last
month, I pulled the light switch on and the tail lights shorted out about 15
seconds later.  It was obvious that something was sapping the power.  If I
turned the light switch off, everything went back to normal.  After
replacing the fuse, all works well until the light switch is pulled.  Then
the short again.  I am hoping someone has some ideas on this.  The blinkers
and brake lights work fine.  I believe it to be the switch.  Others have
said it is more than likely the dimmer switch or a loose ground.  All ideas
will be appreciated.
 
Thanks
