This voltage control box is specified for Austin Healey BJ8 models using a generator and external voltage regulation. It controls charging output to maintain correct system voltage and battery condition.
Yes, if the car retains a generator and control box setup.
Not suitable for:
Mounting hardware and wiring are not included.
Designed as a direct replacement for BJ8 generator-based systems. Charging output should be checked after installation. Wiring condition, earth continuity, and generator health all influence final performance.
BJ8 models use a different control box specification compared to earlier Big Healeys. This unit avoids compatibility issues that can arise when earlier regulator types are fitted incorrectly.
BN1 to BJ7 models use an earlier voltage control box specification. If the car is BN1–BJ7 and retains a generator system, the earlier control box should be used.

No. BJ8 models use a different control box specification and should not use earlier regulator types.
No. Alternator systems regulate voltage differently and do not use this type of control box.
Charging voltage should always be verified after installation. Minor adjustment may be required depending on generator condition.
