    Normal alternator output?

    Have a 99 xj8 that's putting 17v out at the battery terminals when the blocks running. Does that mean the whole alternator needs changing or will I get away with changing just the regulator on the back? Have to say I'm not keen on changing the actual alternator a second time as it is a pig of a...

    Sensor 1 went out both banks?

    Both the exhaust sensors in the manifold started showing 0v at the same time. I'm very very reluctant to believe that this is the sensors as both have gone out simultaneously. I was thinking that I have a wiring fault. Anyone able to prod me in the right direction? Any common trouble areas?

    Soon to be a s-type owner no more :'(

    As many will know my gearbox fault messages are becoming a weekly affair. At the cost of £450 We have established this is probably a tiny clutch slip resulting in the error. But without stripping the gearbox entirely we will never know. Unfortunately it's a £2000 job and there's no way I'm...
