<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I installed an isolated power take-off point on my positive-ground
Norton in order to use newer accessories, like gps. After a few short trips sweating
bullets that I would accidentally brush the two chassis’s against one
another (this is a tow-truck level catastrophe waiting to happen) I gave it up
and converted the Norton to negative ground, like the rest of the automotive
universe. I converted my TR3A during the original restoration. Save yourself a
lot of anxiety and convert your TR to negative ground; there are several good
posts in the archives. The original TR3 harness uses black for chassis ground.
Red is used for headlights and taillights, so there is minimal ambiguity with
the red (hot +12v) cables used in after-market stuff. Job takes much less than
a day. Might as well replace the generator with a decent (and cheap) alternator
while you’re at it, if you’re serious about long trips. If it
were me (and it was), I’d also replace the starter with a modern geared unit;
the old starters give it up when the car is hot. <o:p></o:p></span></font></p>
