Re: Sorry to Butt in..
The great majority of Jaguars were like your LR and carried Positive
earth Generators. In terms of mass production, Jaguar switched to negative
earth alternators with the XJ6 Series I. They did, however, experiment with
a negative earth alternator briefly with the S-Type Police cars in 1967 and
1968. This was done because of the need for additional power demands these
The alternators these cars used were a Lucas #23504. The odds of your
finding one are remote at best. It IS, however, my understanding that you
can take a modern negative earth alternator, and make it positive earth by
reversing the heat sink diodes. Whilst I have never done it myself, I have
been told by many an Austin Healey owner that any competent auto electrics
shop can make the switch.
