battery charge fault

[delvey]

The "SH" is a shunt fuse,

If thats removed with the ign on,everything can become Unpaired from the BSI
Try a BSI reset and see What happens,

Thanks. Doesn't the window need to be down? Plugged planet in and showing no reply from radio ECU. Wipers showing activated in pp2000 as well when moving stixk

[lozz]

Yes. window normaly has to be down,
ithink all thats for is so you can lean in and switch the side lights on as per the Bsi reset procedure.
having someone sat in the car to do that bit might sort that part out,

this Bsi B/s is nothing but witchcraft

Who ever invented it needs shooting

[delvey]

Thanks. Don't have a buttons for locking on the key fob either, does that matter?

Shouidnt matter idont think
unless your programing the R.c.l. imight be wrong tho

hopefully someone else will confirm ?

[delvey]

Tried the bsi reset to no avail
Starting to give me a serious headache. Any peugeot specialists in the Manchester area?

Done some testing yesterday, heres what I have so far. Battery positive to Battery negative with engine off = 14v
With engine running drops to 13.2v, when fast idle stays at 13.2v. After around 10 minutes this dropped to 12.2v
Alternator Positive to Battery Negative 13.2v and when fast idle 13.2v as well
Alternator casing to battery Negative gave 0v, as did Battery positive to alternator positive.
Battery positive to alternator casing gave 12.5v

So, any of the electrical people know what these readings mean?

You hadn't long disconnected it from the charger before making your first measurement,

It isn't charging,

You don't have a wiring problem.

99% your alternator's not working.

Sorry.

You are still welcome to bring the alternator to me for testing, my mate will not charge me....pardon the pun, it wasn't intentional.

BTW, does the 406 have a lead from the alternator to the starter? I recently had a Vauxhall Movano van with a not charging fault which I thought was the alternator until I saw sparks from the starter motor wires, turned out to be a loose wire where the wire from the alternator fitted onto the starter.

The Movano alternator is very similar if not the same as the 406.

Thanks, may have to do that
Not sure about the alternator having a lead to starter

According to SEDRE it does.

Thats what I think, but the swines where I bought it from will not take it back, claiming 'its working just fine'

I may pick a cheap one up from scrapyard to be 100%

You were correct.The place I bought it from finally exchanged it for another, slightly different alternator, even though they said it was still testing ok on the bench. Finished putting it in an hour ago and no more battery light
Thanks everyone for the advice and help
