Jaguar XK140 Wiring Harness Set

Wiring for an Alternator instead of the original Dynamo using heavier wiring. As a rule any Ammeter wiring is also removed as an Ammeter does not give a true reading with a Alternator. Many Ammeters do not have a large enough scale to use with a modern Alternator and the added resistance of having an Ammeter in circuit may damage the regulator of a modern ACR Alternator.

Modification to upgrade the standard Dynamo wiring if using a Dynalite unit up to 42AMP (Alternator in a Dynamo casing), the charging wires and ammeter wires (if fitted) are upgraded to heavier cables to cope with the higher outputs of the Dynalite unit.
