Triumph TR2-4A Battery and Cables
The electrical system and circuit of the TR2, TR3, TR3A and TR4 was positive earth, whereas the TR4A used a negative earth system.
During service, different sized batteries may have been fitted to your car compared to that originally specified.
When the physical size of the battery is changed the length of the fixing ‘J’ bolts may also change.
We list the applications as original and list the lengths, the correct length required should be established and ordered accordingly.
