93 and Later Relay failures

[Michael Neal <mneal@wco.com>]

I just wanted to advise the list of a known problem with late model jags,
roughly '93 and later.  They several Hella brand relays in various places
for different components.  Underhood usage of them seems to be the worse
problem.  The XJS and XJ6 use them extensively on everything from A/C
clutch control to EFI main relays.  Hella apparently came out with a
replacement to "fix" the failures.  They haven't been working.  Whenever I
have a strange problem come in, 90% of the time it's been one of these damn
relays.  Unfortunately I'm forced to replace them with what Jaguar provides
so that's what they get.  The relays are developing bad contacts and
overheat, failure is usually intermittent.  Most of these relays have a
light blue case.  You can trouble shoot them by pulling the relay and
jumping between the 30 and 87 terminals.
