Thanks to all who responded to my question.=C2=A0 I was corrected on the f=
act that Triumph switched to negative ground when the TR-4A was implemented=
(1965).=C2=A0 The TR-4 was still positive ground.=C2=A0 But, the Roadster =
Factory lists the same part number for the TR-4 Generator (205939/AL) and t=
he TR-4A, so my logic is still correct.=C2=A0 Not that it applies to me, bu=
t I wonder if there is any difference when using this generator on a TR-4 v=
erses a TR-4A?
Thanks again.
Jack

I don't want to do anything that will burn out my new generator or voltage =
