I use a smart solenoid(redarc) in my tojo and it works great. Can someone point me to a wiring diagram or pictures or something to show where to pick up the charge wire and/or information on what they have done in their Disco2 to get a dual system working??

Thanks, Rob

Welcome Rob(And your oldies).
I use a redarc on mine and pick up power from the main battery post.
Earth is direct to the bell housing.
I am sure others will know about the "rotronics" unit.

Rob, Very possibly poorly installed, as MOST Rotronics stuff is pretty simple and foolproof. There are better battery management systems out there, BUT the Rotronics one should at least work.

Any chance we can get some pics, and an explanation of the system so we can help further?

If the system "sense" is connected to the alternator charge light, it wont work on a TD5 as it has a battery sensing alternator, it needs to be hooked up to an ignition live which is NOT live during engine cranking.

The D2's come with a 130amp alternator,, more than enough for several batteries
