[quote] Might a switch be more efficient than a relay for the E bus load, assuming a ~10

   Certainly more efficient since the switch does not

   draw current to keep it closed. But the relay is

   called for when it is functioning as a mini-contactor

   located adjacent to the battery bus. If you can reach

   a switch located there, then you could consider the

   subsitution.

  

 What do these little Bosch type cube relays draw? 

 Thanks, Tim Andres



   About 100 mA depending on manufacturer and some

   other details. These are not big energy hogs.
