Question about 2007 Jaguar XKR Convertible
The possibilities in the electrical circuit are a bad battery, bad power connection at starter or fuse block, bad ignition switch, bad neutral safety switch, bad starter solenoid, bad starter field or brushes, or bad engine ground strap.
The mechanical possibilities include binding engine or bendix grear on the starter.
But a voltmeter across the battery and ensure it is 12.5.
When you try to crank it should drop to 10.
If it does not, then current is not getting to the field, so it is before that or the engine ground strap.
If it drops too low, like 9, then see what happens when you stop.
If it comes back up to 12, the battery is good but the starter or engine is binding.
If it does not come back up, the battery really is bad and at least needs to be charged and/or replaced.
