[C320-list] LinkPro problems

[Jeff Hare]

Hi Mike,

As you suspect,  all loads should be connected there. 

You May want to use a heavy duty Negative bus bar here instead of piling too many items on the shunt terminal stud itself.

I connected the charger cable to the shunt and it seems to have fixed the problem. I still don't have the engine
cable connected to the shunt. Should it be? That would be 4 cables on the system negative side of the shunt (charger, battery negative, one from the panel's negative bus, and the engine). 

I would think that without the engine cable connected it would not give an accurate read of the charge from the alternator. How quickly should my stock alternator recharge my system (flooded 4Ds)?

Thanks again - this list has been a savior many times for me.
