I recently installed the cooltech flat tow harness and the rvi towed battery charger.
After the install I noticed that some of my circuits remained active when the battery was disconnected *and* the 3 lugs on the sidewall where disconnected.
I traced the problem to the installation of the cooltech combined with battery charger.
When the cooltech is installed, the ground from the 6 way plug is also connected to the chassis. This is under the passenger footwell. See this picture:
Now when the rvi tbc is installed, the ground from the RV side is joined with the ground of the cooltech.
Internally, the rvi grounds are common, so if you connect the rvi to the battery directly, then it will remain joined with the 2nd battery, and via the cooltech harness provide a ground path.
This could be a real problem, as it is a very small gauge wire and too much load will cause damage.
For safety, I have relocated my vehicle side ground of the rvi to the sidewall posts.
If you leave it connected to the battery, this should be the first connection removed, and the last to be installed.
