Don,

Thanks for this information; it is very helpful to those of us who are
contemplating switching over  to negative ground (or earth).  I have four
questions:

1. if the only vulnerable part is the voltage regulator (my '52 does not
have a radio), can I substitute a proper voltage regulator, i.e., one
designed for negative ground?
2. I've heard that one of the reasons for accelerated rusting of LBCs is
that they came with positive ground.  Is there any truth to this rumour?  I
somehow doubt it, considering the number of rusted Hyundais, Toyotae and
Hondae I have seen.
3. what is the advantage to switching over to negative ground?
4. isn't the engine already grounded through the bolts that hold the engine
to the frame or is the resistance through the bolts too high?

Thanks again.
