Description

The plugpal Inline Blocking Diode is a high-quality replacement and upgrade for original classic car and motorcycle diodes. Designed to prevent electrical backfeeding, this inline rectifier diode is suitable for a wide range of classic vehicles, including:

  • MG B
  • MG Midget
  • Land Rover Series
  • Jaguar

…and many other classic British cars and motorcycles.

 

What Does an Inline Blocking Diode Do?

An inline blocking diode allows electrical current to flow in one direction only, preventing unwanted reverse flow (backfeeding) that can cause:

  • Warning lights to glow faintly
  • Circuits to operate incorrectly
  • Electrical system faults

Commonly used in classic vehicles in circuits such as:

  • Handbrake warning light circuits (e.g. MG models)
  • Headlight circuits
  • Auxiliary and modified wiring applications

 

 

Direct Replacement for Original Lucas Diodes

This unit is ideal as a replacement for original Lucas components and features:

  • Male 6.3mm brass spade connector (Anode – A)
  • Female 6.3mm brass spade connector (Cathode – K)
  • Correct orientation for direct replacement installations
  • Durable ABS protective enclosure

When used as a replacement for an original Lucas diode, the connector configuration ensures correct polarity and simple installation.
