[AT] A question for the electrical wizards

[John Wilkens]

This is partly on topic because it involves my mostly dependable '78 
Ford trailer-pulling pickup........  I need some ideas about what 
could be causing some odd problems with it----namely, my dash lights 
are very dim, the light in the tach quit all together, the rear turn 
signals work but one front signal is dim and slow, and the other one 
is dead.  Other stuff seems normal.  Someone suggested I had a ground 
problem but what exactly does that mean, and how do I find/fix 
it?  Hey, any ideas for me?....please!      John W.
