Why is my JAG engine not cranking up?
This environment is tough on terminals and dirty, loose connections here are a common cause of “no crank” conditions.

Loose, dirty connections here are a common cause of battery run- down.
Why is my starter not working on my Jaguar?
Some models may have a white/blue wire at the relay which by-passes the ignition ballast . It has no direct bearing on starter operation. 7) If all these voltage checks are OK then you likely have a faulty starter relay. You can opt to replace it or, if desired, disassemble it and clean the contacts.
