Battery light on - eamon - 20-09-2013
Hi all,
I have a problem with my 1.4 petrol 306. When i turn the engine off and take the key out the battery light stays on, it is only very dim. My electric windows also still have power. Anyone got any ideas on what could be wrong and what I should check?

Check the earth point on the right of the accelerator pedal, mine did this but with the stop light :/

or the alternator back feeding.
but earths be a good start!

On a TU, I'd almost guarantee it'll be the gearbox earth, they're always coming loose for some reason.

Can see why a loose earth would cause the windows to still work, but it is french...

I have checked the earth at the pedal it's good, as is the main from the battery. How do I locate the gearbox earth? I am inclined to think it couldn't be an earth as the windows work with no key but the radio and wipers won't. It's very strange.
How do i check if it is alternator feedback?
I have disconnected the battery for now as I need the car for a couple days and don't want it dying overnight :S
Also the battery light goes completely off when the engine is running

check all fuses. ensure they not blown/refused themselves.
check connections on the left hand chassis leg

Negative battery terminal, one of the wires will go to the chassis. one of the wires will go down onto the gear box, make sure both of those connections are clean, and make sure your battery terminals are clean and secure. Whats your battery voltage like?

hey all, I found the problem eventually. After checking everything else i decided i'd check the alternator. The diodes when blown, got it reconditioned and everything is fine now. thanks for your help
