So, the TVMS has this programmable feature? And the TVMS "talks" to the Isolator? Pretty cool. Still wondering why the battery voltage goes to 11.5 or lower when the heater kicks on. Might need fatter wires? Also, which battery is it monitoring? I suppose it should monitor both sides and disconnect when it hits that threshold. I can understand that they would not want to lower the threshold any more than 11.5V is already pretty low.
I'm glad you got it figured out and are warm now!
