MGB Upgrades & Alternatives

The MGB’s original electrical specification was designed for a car used in a different era, and there are several areas where modern components or carefully chosen upgrades make a meaningful practical difference without compromising the car’s character. Battery chargers and conditioners protect the investment in replacement batteries during periods of inactivity. Hi-torque starter motors provide more positive cold starting. High-output alternators provide increased charging capacity. A hazard warning light and relay kit brings pre-1974 cars up to modern safety expectations. Performance ignition eliminates the maintenance demands of the contact breaker system. Lighting upgrades cover halogen conversion, relay-based headlamp wiring, and enhanced-output bulbs.
