1985 Jaguar XJS

PICK-UP COIL-TO-RELUCTOR AIR GAP
Normally, air gap will not need resetting unless it has been tampered with. Always use a plastic feeler gauge when checking or setting air gap. See Fig. 2. Gap must be checked at each reluctor tooth.
To check air gap, align reluctor tooth with pole piece of pick-up coil. Insert proper plastic feeler gauge. On XJS, set air gap at.007-.015" (.18-.38 mm). Check gap at each reluctor tooth.
To adjust air gap, loosen pick-up coil mounting screws. Align reluctor tooth with pole piece of pick-up coil. Insert proper feeler gauge and move pick-up coil against gauge. Tighten mounting screws.
