Tried a different battery last night, to the one I'd usually use. It's a Halfords 12v maintenance free battery. Not brand new, it was purchased in 2002, but holds better charge than the one I've used since I bought my C5.
My problem is, that when I connect the Halfords battery and switch on the C5 to the 'on with lights' position, the pod is dead, and the front light comes on just a little.
When I switch the C5 to the 'on without lights' position, the pod lights up, and the motor runs normally.
What's happening?
I'm sure I'm connecting the battery the right way round. I don't think it's possible to connect it wrongly with my C5 wiring kit, but would like to know if others have had similar problems?
