[Boatanchors] Partially Off Topic Questionþ

[Carl]

>From 1928 to 1953 (1954 in Canada, Australia) all Fords were 6V positive 
ground.

Converting to negative ground is very simple. Reverse the ampmeter leads, 
coil wires, and battery terminals. Repolarize the generator by lifting the 
field lead off the regulator and momentarily touching to the battery 
terminal next to it. The engine must be off.

The above works with all 46-53 Fords that are standard with internally 
grounded regulators. Im not sure about earlier ones. Other makes sometimes 
use externally grounded generators and the repolarization procedure is 
slightly different.
