Hi all. Can someone help/advice ? Doblo 1.3 D 2005 ex Wheelchair van with low mileage suffering from battery drain

Done usual advised parasitic draw tests as best I can with multi meter/ remove fuses etc The one that seems to make difference is a 3A inline fuse in small plastic holder connected to positive terminal of battery. Short orange wire and then goes into harness . What does it feed ? After removal all things seem to be working?

Doesn't ring a bell, any chance of a photo.
Do you suppose it was related to wheel chair side.
What amperage? I had an Iveco Daily that used to bring on ign. light a few minutes after locking and walking away, finally traced it to someones after market alarm feed from brake pedal switch.

Thanks for reply. I think the previous wheelchair use may be it. It has winch and some time of alarm - will check when home . My son tested with meter but I think with 10amp selected and meter in series on negative terminal/ post it read about .5 ( not 100%) sure pulled all normal fuses, no change until I pulled this 3A one then draw dropped. It also looks slightly different colour wire + so may be add on but does seem to go into original harness a few inches from battery. If I can find out what it feeds I may be able to progress

I agree , it doesn't look factory , plus those heavy duty wires on positive side of battery are presumably for the winch also.

Maybe strange question

Sorted out parasitic draw on 2005 Doblo 1.3 D as shown in previous post &photos. There was a slightly different colour orange wire and inline 3amp fuse been added. Pulled fuse and battery discharge issue solved (still no idea what it was feeding everything still works – suspect something to do with wheelchair stuff) but now have a query which may just be me, or again fact it is ex wheelchair vehicle

On Dash with headlights on blue normal symbol to show that all OK

Switch to dipped beam and in same bulb spot the blue main beam symbol changes to a light blue flashing symbol of two parallel lines - same place as main beam bulb

BUT - and this is bit I cannot understand - only at night and only with vehicle moving. Stationary with lights and engine running on or in daytime with - no flashing light. Seemed to only come on as it gets dark ! Keeps flashing every second or so. Is there some kind of sensor?

Am I cracking up? No handbook but searched online ones found nothing Help

Does sound strange, never seen that.
Have you disconnected all non standard wiring as far as you can tell?
Apart from that any chance poor earthing around headlamp area causing a back feed?
I don't claim to be an Auto Electrician.
Other than pulling fuses one at a time when the issue occurs. Sorry.
