Disco 4 Dual battery issues - Battery drain

Tommy Armstrong · 8th June 2020, 06:00 PM

Update - Tim from Traxide helped me see if the health of both batteries are good and turns out they are. So I'm now in search of power drawing from somewhere. Problem is I've got no knowledge in how to find it with almost zero knowledge on how to use the multimeter. Is there anyone in the NSW Central West area with experience that could show me? I'm also heading to Melbourne in a week. I'd like to learn. Thanks.

You don't have a brake controller do you? Mine used to draw enough current to flatten the battery over a couple of weeks.

I have exactly the same issue and set-up. But batteries are always dropping without obvious devices causing power consumption.

But to answer the previous post, I also have a Tekonsia brake controller. So I need to unplug and see if that is the silent consumer.

Mine was a Tekonsha as well. It doesn't seem to flatten the battery as quickly in the Defender but I wonder if it is a cumulative effect with the Tekonsha adding to the problem. We were overseas for a month and the Defender was pretty slow to start, also the drain on the battery starting the Defender would be less without climate control and other systems waking up when the key is turned on.

Now having the Redarc I realise that my previous Tekonsha units x3 were.. well..rubbish and yes they drain power unless wired via a relay 😞

Does the screen stay lit on your Tekonsha when stopped?

I agree. Having moved from a Tekonsha in the 3 to the (already installed) Redarc in the 4, I'm amazed at how much better the Redarc is.

Yup..same here was fitted to the car.. I can set and forget whereas the Tekonsha was alway doing weird stuff like locking all the wheels at low speed braking ...so back off..and then not working at all.

Tried all sorts of settings and mountings but it did the same stuff. I have one in the tractor and it is just the same as the ones in previous cars..weird🙄

Bin it. Redarc tow pro elite so much better!! No drain issues and works a treat, plus the remote head means a neat install.
