no it shouldn,t but the charger should shut off after 16 hours thats how its designed and i don,t think the breaker is going to effect that at all......your charger worked before right?.........i,m not sure what to tell ya to do because what your decribing the charger now not shutting off is an indication of 2 things that i know of........1 being a bad OBC and you said yours is new ( unless its defective ) and thats possible and 2 the low voltage sensor in the charger being bad and you say no one has messed w2ith the charger........i know of no other reason that your charger wouldn,t shut off ...........even with bad batteries it would timev out and shut off.............so alright guys anyone have anything else i,m missing
or am i wrong or what
the battery light if it works or not wouldn,t effect any of this.........maybe someone else here can add to this
but i,m kinda scratching my head right now............................
