[Mgs] positive to negative ground

[DONALD TOY]

Sages of the List,
I know this has been covered time and time again, however I'd be pleased to
hear the particulars one more time in detail. That way if I decide to go ahead
with it I have a smaller chance of screwing it up. What is the procedure for
changing over from positive ground to negative ground? I have a 1954 MG TF. I
may want to install a radio and put a 12 Volt power socket for cell phone
charging etc.
Thanks in Advance,
Don Toy
