X250 Battery Drain.

Last week I went to start the MH and the battery was dead, completely dead.

After jump starting the van we set off on our way, with suspecting that the battery had finally given out as I had suspected it was on its way for a while. We got home OK because on hook-up, the vehicle battery is charged from the Elektroblock (EBL20-2).

When I got back on the Monday, I went and purchased a new battery and fitted it, everything seemed fine. Went back to the van on Thursday, battery almost dead, turned the engine over slowly but then died before it started up so needed a jump again.

We again went away and when leaving the site, the Van started perfectly due to the charging.

I disconnected the battery when the van was back in storage and today when to carry out some testing.

When connecting up the battery, there are a few clicks from a box mounted in the battery area and a draw of 0.4amps for about 30 seconds and then another click and the current drops to around 0.15amps which will still drop the battery to 50% in just over a week.

The next steps when I get time is to start the fuse removal process, I already unplugged radio and this made not difference.

So my first question is, does anyone know what this unit is? It's connected direct to the battery with multiple cables going off and then multiple connections to the negative terminal as well.

The black box looks like you have a towbar fitted.

I do have a tow bar fitted. So if I turn on indicators etc, I should hear more clicking inside said box.

There is absolutely no markings or labels on this box but as I don't use the tow bar, I could leave this disconnected.

Thanks, I'll check this out

As above....Relay unit for the tow bar. If it's connected correctly you should hear an audible beeping when signaling left or right when connected to a trailer or toad. It should not pull any current unless connected up with the ignition on or lights on etc

Maybe, maybe not, as depends on how your box of tricks is handling the load from your trailer indicator bulbs to obtain the one per second flash and as above when the trailer is connected.

My box does not beep, but I get a visual indication on the dash when the trailer indicator flash.

Never connected anything to the unit so not sure if it beeps.
I need to do more digging but at least I know what that unit should be.

Had a tow bar wired up on my toad by Taf when they fitted the a frame. He wired the relay box through the ignition to save a drain when parked up.
