If you are planning on upgrading from a dynamo to an alternator (or even, but not really likely, a dynator) for your older-type kit possibly featuring (but not restricted to) a Ford sidevalve engine but don’t want to modify your wiring loom or you’d prefer to keep the engine bay retaining its as-original look then 105-Speed has the answer with this Lucas-style ‘dummy’ voltage regulator.

It’s a direct swap for the original – and redundant – regulator and has the added benefit of a 50-amp fuse on the charging circuit.

It has an RRP of £59 and is available via www.105speed.com or at the other end of 01234 826 827 ENDS.
