When I'm idling and I put my foot on my brake my dash, head and rear brake lights dim/flicker dimmer.


It's strange, when I press the brake just enough for rear lights to come on the headlights dash and brake lights flicker/dim really quickly for about 2-3 seconds like it's surging/draining power from somewhere.

And if I press the brake, let it flicker, then let go and quickly press brake peddle again it doesn't do it, it's like it has to build up some sort of charge?

My rev counter needle also jumps up quickly then back to its position often, even with just key in to position II a and not started.


Any ideas please?

Thanks
