	Do a volt check at 2k, and it should be putting out about 14.3..this is a healthy Alternator!! If when the battery charged, disconnect both leads and do volt check, if you see it loosing charge, there's dead cells in there some were and battery needs replacing. If it hold charge for a short period of time, you then have a drain some were on the car! this is when I start to check for bad earths and shorts. :thumbs:

	Do you mean battery light? Corsa doesn't use an alternator light, not sarcasm. Just not sure if you're used to working on Corsa's or other cars Cheets

	This is alternator earth Speedo problems at the moment, so speedo itself it out, and needs quite bit of wiring to work. So can't check that

	If its dropping as you measure it, that may indicate the battery is knackered. Alternator not charging would normally give you a battery light.

	Check earth lead to alternator

	Just to add, Battery been on charge for about an hour, thought I'd use multimeter to check power. It's now up to 13v but is dropping is as I look at it? This because I've just taken off charge? Or something else? Let battery charge for about an hour, started car first time, it's only 11 volts odd with engine running, and that figure slowly dips. So must be a case of alternator not charging battery. This is where I get lost, electricity wise, [Edited on 11-12-2013 by Generation]

	Started the corsa today (c20let) and on idle it cut out after about 3 mins. It alsodidn't have enough power to try and restart (barely and really slowly turned over) I read the fault codes, and got error 48, which is low battery voltage. So used mutli metre to check Voltage and it was 12. Something, but didn't even have enough power to Do up electric windows, Ideas on issue?
