When I took on my S-Type there was no sign of the long bolt which holds the battery in, just a rusty stub sticking out underneath and a Halfords receipt for a new battery with the documents. The battery was 'held' in place by a daisy chain of cable-ties. This looked like a potential MoT fail to me. Not having seen the system as it should be, I drilled and tapped the remains of the captive bolt in the boot floor and put a new 1.5" long bolt in from underneath. Now the plastic battery retaining block is held by a nylok nut and the threads are inside the boot. So the bolt head can rust all it likes under the boot floor, I won't be touching it again for the life of the car.

Recently I solved a water leak from the pipe union between the expansion tank and water hose. This was dropping coolant and in turn causing the alternator to become soaked. If the windings are wet then sparking will occur and the charge output will drop. Now the engine bay is dry again I noticed the battery charge has improved and I can put off buying a new battery for the time being. I really think s-type owners should check around the top of the radiator and the fan housing for any sign of water and if found deal with it, this is particularly relevant to charging issues.

S Type..XS 2006 Just had the same secondary alarm bleeping problem...had to get up twice in the night and realised the only way to guarantee it stopping was to leave car open. Read the forum and thought it seems like a bit of a faff......so rang my local Jag specialist and took it straight in for investigation. He took the drivers side plastic inner wheel arch cover off, disconnected the delphi unit...replaced cover...10mins work and charged me £10 What was I worrying about?????
