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
needed?
