Jaguar Repair: Positive Ground, xk150, xk 120

Question
Can you tell me which jaguars models (by year) used positive battery ground?

Answer
HI Mike,
All Jaguars, XK-120, XK-140, XK150 and the early E-type were positive ground. As I remember, the first negative ground cars were the cars using an alternator. I think the same was true in the sedans. The generator cars could be switched as I had to switch many over the years for various reasons. If you want to switch one, read my section on "Tech Tips" on my web site, http://mg-tri-jag.net
