Hello all,

I have a friend who has a 48 AD that had been converted to 12 volts by the 
PO.  The wiring harness kinda resembles a nest of either a common brown 
mouse or else a kangaroo rat.  His fuel gauge doesn't work and I am trying 
to get it going.  I have scanned the archives and think that I can get it 
working by supplying the 'full side' of the gauge with 6 volts and then 
going to the sending unit to ground.  If that ain't right please let me 
know.  I don't have a wiring schematic.

I do have another question about the 12 volt conversion.  How many reducer 
resistors are needed to run all the 6 volt accessories?  Right now there are 
three reducers installed - one to the heater, another on the firewall that 
feeds ????? and another under the dash that feeds ????.  He has another 
reducer to install for the fuel gauge but I don't think he needs another 
one.  All the reducers are store bought and read 1.5 ohms.  One archive said 
that the reducer should be 30 ohms at 2 watts.  What is right?  How many are
