Triumph GT6 Electrical Parts

Triumph GT6 Electrical Parts

Triumph GT6 electrical parts cover everything the Lucas system needs to keep your 2-litre six-cylinder running and your lights on. Built between 1966 and 1973, the GT6 used negative-earth electrics across all three marks, though Mk1 and Mk2 wiring harnesses differ from the Mk3 in routing and connector layout. Getting the right spec matters.

Browse our GT6 Battery range for correct-fit replacement cells, then dig into GT6 Electrical for ignition components, wiring harnesses, switches, lamps and charging parts. Ignition health directly affects engine components, so it's worth sorting the whole system together. The fuel system relies on accurate sender and pump electronics.

Rimmer Bros, established in 1982 and based in Lincoln, UK, has stocked GT6 parts for over 40 years. Shop your GT6 electrical parts here and get them moving fast.

Frequently Asked Questions

Are GT6 electrical parts the same across all three marks?

No. Wiring harnesses vary between Mk1/Mk2 and Mk3 models due to routing changes. GT6 Electrical listings confirm mark-specific fitment for each component.

Can I upgrade the GT6 ignition to electronic points-free?

Yes, electronic ignition kits are available for the GT6's Delco distributor, improving reliability and removing the need for regular points adjustment. They're listed under GT6 Electrical.

Will a faulty wiring harness cause starting problems?

Degraded insulation causes voltage drops that hit the starter, ignition and instruments hard. Check the GT6 Battery condition first, then work through the harness from there.

Do GT6 wiper and washer electrics share the main harness?

Yes. The wipers and wash system motor and pump are fed from the main loom, so harness condition affects their operation alongside the rest of the car's electrics.
