Peugeot 106 XND - battery discharging! - zironxl
Hi everybody. I've got a problem with my Peogeot 106 XND (N reg) and wondered if anybody else in here can confirm my suspicions.

Intermittantly the battery experiences rapid discharge when the vehicle has just been parked for 20 mins or so.

I've swapped out the battery (I own 2 106 XNDs!) and eliminated it as being the source of the problem.

Battery is a 65Ahr battery. Battery intermittently goes from fully charged to complete dead (not even enough power for the internal lights when door is opened) in about 20 mins. Note the term intermittantly! Battery is warm to the touch when this occurs - so something is causing a massive drain by means of a short... - using 20 mins as a dischage time and 65Ahr whatever is draining the battery is consuming at least 180A!!!

No fuses blow when the battery discharges - so I am certain the problem is before the fusebox.

Looking at the Haynes manual wiring diagrams the only components before the fuse box are the starter motor and the alternator.

I've visually checked the live wiring from the battery terminals to the above components - looks fine.

Since the problem is intermittant (can room fine for a cpl of weeks then the problem occurs) I am suspecting that either the starter motor or alternator is somehow positioning itself internally to cause a short.... (in terms of brushes in contact with each other ?)...

Can anyone confirm my thoughts above or suggest anything else that it could be? Like I said - I know that the battery is defo OK.

Look forward to some replies (I hope!!)

sorry - just read the above back and noticed a mistake - the line (can room fine for a cpl of weeks then the problem occurs) should be (can *run* fine for a cpl of weeks then the problem occurs)!! :-)

When it happens and the battery is warm to the touch is the Alternator or starter motor solonoid also warm. Agh just realised this is a Desiel, most probable cause faulty glow plug heater timer relay, been there before. Regards Peter

Thanks Peter... Just checking over the haynes manual now (wiring diagrams)... missed the starter glow plug control unit (helps if you look at the diesel page and not the petrol one!!)

Intriged to know what you mean with 'been there before'...? Assuming you had a 106 diesel that suffered this once over too?

Yes I've seen it before but it was a Mondeo TD that had a faulty glow plug relay. As you are aware something is pulling a lot of current from the battery and flattening it pretty quickly but clearly not a short cct. The glow plugs (4) pull 50 to 70 amps and do not go via the ignition switch so an inspection of the relay essentual. Look at the tread on the Merc fuel pump relay and possible causes. Regards Peter

If you cover no more than 100 miles per day and have easy access to a charging point at home or work, then an EV is ideal for you.

Is an electric car right for me?
