My last electrical question was too easy - bike electric tricky one!

Thanks Rich, I was hoping to have it self contained with only one set of wires coming from the battery. I understand your point that the negative can be the same one but I need to try to get my head around who it would look. I'll redraw it as one.

Thinking again - I wonder if I connect the positive side of the charger to both the positive busbar and 87a. In that case it will charge in on and off.

For the trickle charger I will connect just to 87a and negative bus.

Does that sound correct?
