Just fitted a new Battery, even though it is a few more CCA amps evrything works fine apart from the left indicators which sometimes flash quickly. Bulbs replaced but still doing it. Any idea's anyone
I would guess it's probably one of the two bulbs in the front indicator.
It cant be anything 'global' or both sides would do it, so it has to be specific to the left turn circuit. It may appear that front , side and rear are all still working, but I would suspect that one of the two is dodgy That's what I once had.
Have you tried swapping all the left bulbs to the right and see if the problem moves ?
