Hi all. Can anybody help me. It’s had a new alternator and the battery is good.
I can charge it and this morning on the way to work my alternator kicked in and started giving me 13.7v when I stopped it and started it again it won’t kick back in so running the battery down continuously.
Can anybody help please

I'm not an expert on alternators but my first thought would be to check the basics such as fuses and relays. Have you done these basic checks?


ps: this is the correct location for this question; you appeared confused by also posting elsewhere.

pps: which year/Series Captiva is it?

Unknown fault code B57D
I’m lost. Can put any light on the issues. All fuses checked and good.
Alternator not charging unless straight after a charge. When I switch the engine off once then it won’t charge at 14v it just starts at 12v and drops as if the alternator is not kicking in.


If there is any experts out there could you please help me
Thanks in advance

Re your DTC’s B357A and B57D, seems you’ve got it wrong, there is no B57D so think you mean B357D. In any case both of these DTC’s refer to an auxiliary PTC heater which your car doesn’t have if it’s a standard UK spec.

Your problem could be as simple as a faulty voltage regulator in your new alternator or it may be related to poor connection(s) and/or high resistance within the control and charging circuits.

This is not a comprehensive list but it’s a start:

Simple things first, how clean and secure are your battery terminals?

On the series 2 Antara / Captiva there is a multi-earth point connection on the bulkhead just aft of the vehicle battery. If yours has the same, loosen the main connection, move the wires around to make sure of their grounding and re-tighten.

I believe there was an issue with the alternator plug on these vehicles, you may find the connector is breaking up internally especially if it was roughly refitted at the time of alternator replacement.

Check the cabling between the starter feed solenoid which continues to the alternator output terminal, it’s a particularly cheap and nasty arrangement and prone to poor connection/overheating and high resistance.

Get the Alternator, relay(s), fuse(s) and belt checked. Any diagnostic codes ?

I know this is a very old thread but it's the only one I've found that is exactly the same problem as I have.

I've found the wires behind the battery and I can't see a problem with the alternator connector.

Background, battery died and the AA cane out to us. Tested the alternator and battery and said the alternator was putting out 12v while idling and 10v when all lights heated seats etc were on. So he said we needed a new alternator. We had the garage parts and labour cover with them so they booked us into a halfords (yes I know!). But hardly any garages accept the AA garage cover now as they wait to long for their payment. Halfords took 2 weeks to change it! They had the wrong alternator arrive the first time. Then after changing it and us picking it up the manager said an odd thing at the time about how he thought there was an electrical fault as the nee alternator was only putting out 11.5v and was showing a higher reading when the car was off that when it was running. But they didn't know why and it should be OK! if not get it looked at somewhere else because they "don't deal with electrics". Went out to the car and it wouldn't start. The battery had drained since they finished working on it 3 hours before I got there. They kept the car and changed the battery. Assured me all was good and I took thd car home. Drove fine, parked up gif the night. Next morning battery dead and wrong start. Charge the battery to full and it drains it over night. The AA and Halfords have washed their hands of the problem and I've already considered the legal route and I'm not going to do it.

So now I'm hear hoping the real experts (you lot) cam actually give me some good advice.

Added car info to signature as it won't save in the account part before anyone brings that up.

There is a similar topic of battery draining when engine not running. Member Victor suggested the following. "No quick snappy answer. Could be a faulty module staying active and not going into sleep mode (alarm, EVAP, keyless entry, central locking etc) or a faulty alternator diode pack. Suggest you carry out a parasitic drain test first then start pulling fuses / relays to see if you can narrow it down".

I had almost exactly the same symptoms and it was plain and simple the battery connector was broken on the negative side.
