Powerlite Dynamos

Powerlite dynamos look like original Lucas units but work like modern alternators. They're Dynalite conversions that keep your classic's authentic underbonnet appearance but deliver the charging performance you actually need.

Why choose a Dynalite conversion?

Your original dynamo can't cope with modern electrical loads. Add heated screens, upgraded lighting or a modern stereo system and you'll find yourself with a flat battery fast. A Powerlite dynamo solves this by charging properly from idle upwards, giving you reliable power even when everything's running.

These units drop straight into place of Lucas C39, C40, C42 and C45 dynamos. Because they're self-regulating, you can remove or bypass the old control box entirely. We stock both positive and negative earth versions, so they'll work with your car's original electrical setup. They complement Powerlite alternators and Powerlite starter motors if you're upgrading your entire electrical system.

Which one fits your classic?

We have Powerlite dynamos for Triumph, MG, Austin Healey and other British marques. Depending on which Lucas type you're replacing, output ranges from 40 to 60 amps. That's up to 80% more charging capacity than your original dynamo, but they weigh about 40% less.
