[C36IA] Link 10

[Bill Hague]

Tom,
I think what you are saying is that zero , or a small negative number is a good indicator. I think I have finally got it right.
Thanks
Bill

  Bill,
  1. Yes.  Both negative leads from the batteries should come together at one end of the shunt, and then the other end of the shunt should go to the engine ground.  
  2. From memory (I hope I'm not confusing my Xantrex XBM monitor with your Link 10?!), the AH function actually counts UP to zero as the batteries are being charged.  IOW, if everything was set up properly and you start with fully charged batteries, and you have used 100 AH, the link would show -100.  If your charger/alternator put 75AH back into the batteries, the link would show -25.  Being on a mooring you may never see it, but when the link reaches 0, and the charger is still on, the link actually counts UP into positive numbers for a while.  As soon as the charger is turned off, and a load is applied to the batteries, a positive number on the link will instantly go to 0, and then go to -1, -2, etc.  You should never see 440 on the link.  You might see -300 (not good!), or +25 (seldom, but possible), but to see -440 means that every single amp has been drained out of the batteries.  The reason the instructions tell you to f ully charge the batteries first is to have a starting point for the shunt/link to keep track of the AH.  I suppose in theory you could start with a battery that is half dead, hook up the link, and from that point forward the link would think that the half-dead state of charge is "full".  Not what you want.  Hope this helps.

  I have almost got it functioning.A few more questions:
  1)Since I have switched to GC I assume that in addition to having them wired in series I must also have them in parallel for the link 10 to monitor them as 1 bank?
  2) I have changed the factory default settings for Ah from 200 to 440. However from what I gather from the manual, I must charge the batteries until the far right LED starts flashing.Will the Ah function go up to 440Ah and then go up and down as Ah are used and replenished.
  Must the shunt sense the Ah going in before I will get the 440 Ah reading.
  Some day I hope to understand this electrical stuff !!
  Thank you,
  Bill
