jimrankin Posted February 15, 2014 Share Posted February 15, 2014 As a past owner of three MGA's, a Morgan and still own a Jag I can attest that all of the credit to George for being "the Man who invented darkness" is well founded. As if Lucas electric's weren't enough of a problem the Jag decided that positive ground would be even more fun. Try finding someone to sell you a positive ground fuel pump that bolts to the frame so you can get home. Yeah, missed dinner, and breakfast and lunch.....

Positive ground is a bit like anti-matter isn't it? Link to comment Share on other sites More sharing options...
Off Road SHO Posted February 15, 2014 Share Posted February 15, 2014 But there is a positive note (no pun intended, it just happened that way) to positive ground systems, but I can't remember it right now. Let me think... Tom Link to comment Share on other sites More sharing options...

That is one of the uses of duck tape, insulating negative ground components from positive ground. Link to comment Share on other sites More sharing options...

jimrankin Posted February 16, 2014 Share Posted February 16, 2014 Since the power is always at the component, through "ground", all the power is carried through the frame and body, so you, in theory, don't need as heavy gauge a wiring harness. Of course with George Lucas components involved it probably just means the frame will heat up and turn red hot while your driving ;-). Link to comment Share on other sites More sharing options...
