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.
