Misc: Electrical (General) LED Indicators

[highbury731]

I have not seen a positive earth Vincent, Norton yes, but not Vincent.

I must be electrically insensitive, as I can not tell them apart.
When I put my Norton back on the road, I wired it negative earth, and flashed the dynamo to suit. It would have needed flashing anyway, as the genny had been on a shelf for more years than I care to remember. Eventually I reversed the ammeter wires so that charge and discharge showed the right way round. That was a waste of effort, as the needle fell off. Pattern spares......

My Rap then was restored with the original positive earth configuration.
LED’s are polarity sensitive so will need the right ones. Maybe best to get all the parts from Paul Goff’s Site although
the flasher units won’t be self cancelling.
Not going to be a quick job.

I thought all rivet counters kept to positive earth as all were originally (else deduct 3 concours points) except according to the new testament (KTB) "most series D had negative earth "
seriously I guess all B& C are now negative earth but it aint what PCV intended as far as I remember

I am seriously confused by this, both the Vincent handbooks that I can lay my hands on, Sixth Edition 1952, and Eigth Edition 1955 clearly show negative earth in the wiring diagrams, as does Paul Richardson in his book, surely they cannot all be wrong.

Now you have got me really confused Tim, I thought it was the other way round, and so did Paul Richardson, page 135.

Quote KTB
"although the diagram (in the spares list and vincent motorcycles) shows positive earth most series D have negative earth"

Of course I have neither of those other books to hand.......
so I to am ?

I see the D Series harness diagram shows a positive ground, hence the reference in KTB to this detail.
Many years and I never noticed that MO108.
I show negative ground for A,B, & C Series.

 

[Peter Holmes]

That is my understanding also.

 

[vibrac]

Yes + earth B &C but I bet there are not many that way nowadays....

 

[Peter Holmes]

Just for clarity I think it is negative earth for B + C series and positive earth for D series.

 

[Peter Holmes]

Mine are, I would not have them any other way.
