Electrical?!

[Tringaling]

Right i use my iPhone to play music through my stereo, it randomly started skipping on cd and aux inputs..

It only seems to happen when i press the pedals, i am mega confused!

I have taken the unit out and reconnected it but still nothing?!

Could it be an earth or can anyone point me in the right direction please?!

Turns out its an earthing problem as also my interior light flashes when i put my hazards on!

How much approx is it for a new earth from
Battery to gearbox?!
