Hi to all,

I am installing a double battery.
Checking on the relay I find the #30 not doing anything, whether the alt. charging or not.  No current.  
I assume, since it is the largest Red wire, it supposed to be hot sometimes.  
Would one say, the relay is bad?

87 both of them Hot all the time
85 is Hot when charging.  I assume to connect the second battery to it.  
86 ground
30 does nothing
