FYI - the Classic KB is available now...

I have tried to be accurate and complete with information from my systems and customers.
If you find anything wrong or missing or incorrect please let me know so we can get it right.

Just a heads up,

I tried removing the connection between the last slave and the system master as an experiment, and Jim is right, does not work for everyone.
The master went to resting at 100% SOC but could not get to float because the 3 slaves were still absorbing. Once I reconnected the cable, all 4 instantly went to float.
All 4 are showing revision# 2193/2186

Using the Whizbang Jr. on the master to go to float when end-amps are reached.

Check your cables...
It sounds like you are sending from master-1 to slave #4 instead of receiving from #4.
Then 4 sends to 3 and 3 sends to 2.  Backwards around the loop...

Take all the cables out, set master-1 to BTS MASTER and the rest to BTS FOLLOW.
Put BTS in Master-1
Set 2,3,4 MNGP to TEMP page and watch battery temp. 2,3,4 will say N/A
Then plug a cable from master-1 to 2 and see if the battery temp gets sent from master-1
If not the cable from master-1 to 2 is either in the wrong jacks or not a good cable.  Do the same from 2 to 3 and 3 to 4, the battery temp should follow to all 4

Everything checked out...almost.  The cable from CC#3 back to the master was in the "out" jack".
Just swapped them, and will run like that to check operation - and then try pulling it out, per your FAQ.

Thank you

Rob
