F guages

[Lindsey Fuller <lfuller@xxxx>]

noticed a curl of grey smoke inside the left side of my astrodome on 
startup a few days ago. did a cursory check & all guages light as before 
& work, except the ammeter guage acts up a bit more than before (but 
still seems to work most of the time) and it is now "lazy" with ignition 
off-sits about 1/2 way to discharge. system is charging @13.5 volts. I 
suspect a small wire burned up in the ammeter. Any ideas as to what it 
might be or if the guage can be repaired? Thks
