Bongo Fury

Hi
We have a 2.5 D Bongo which has started getting a flat battery.
By putting an ammeter in series with the battery I found that removing the 40A BTN fuse causes the drain (0.02A) to stop.This is the central locking fuse so I can't really see how there could be a drain in this circuit as the doors are either locked or unlocked.
Please can anyone assist?
Thanks,
Martin

Has it got an alarm on it Martin?
If so it may be that.

Faulty actuator?

May be worth disconnecting each one in turn to see if it stops draining. There's only 3 to choose from....

Edit : Stick a meter on amps in place of the fuse, and open the sliding door. That will disconnect the actuator, so a quick way of eliminating that one.

Hi,
does this 40amp fuse control the strip light in the back of the vehicle,if so I have heard of the tube/gubbins draining the battery over 2/3 days.

Cheers.

The 20mA discharge you report isn't going to flatten a fully charged starter battery in a couple of days, three possibilities;
1. The battery isn't fully charged to start with - Have you charged the battery using an external charger for at least 48 hours to get a decent charge in the battery to start with ?
2. The battery is knackered and needs replacing - if after a full charge as above the battery still gong flat with a 20mA load then its time to replace it.
3. Are you sure that you didn't just measure the discharge in the BTN fuse circuit ? How did you measure the total load on the battery ?

Hi
Thanks for all the help.
There is no alarm fitted.
The battery was 'dead' ,but as it was the one we got with the vehicle about seven years ago that's pretty good.
However we only use our Bongo once a month or so which means small drains add up.
Annoyingly the tube was on but it wasn't the fault.
I started off by removing the positive lead from the battery and measuring the drain but when I found it went when the BTN fuse was removed I've been measuring across the fuse holder.
If I remove each actuator from the circuit, where are the connections? Do I have to get into the doors or is there a connection in the passenger compartment?
Any more ideas appreciated.
Thanks again,Martin

Fit a simple battery isolator to the battery terminal. No big hassle or cost.

I have simply pulled the fuse but would prefer to fix the underlying problem. Interestingly the glow plug light now flashes continuously!Nothing else seems to be affected.

There are two connectors on the door wiring harness which are accessed by removing the plastic trim at the edge of the wheel well. Undoing one will, I guess, disable more than one system in the doors as there are four circuits I can think of.
