Yes I want to use EMON to control the charging, but it is not working for me, Vref & Iref are all connected but still does not work Why?
If you look back at our threads you will see that I did tests with Vref & Iref connected and once unconnected.
Even when I did the test with them unhooked, the voltage dropped to below 13.20 V when it was supposed to float at 13.40 v why?

What do you have Vref programmed for, and are you getting 1/10 of that on the Vref line?

When I did tests with the TB-2-4 on the V2 connected to the TB-2-8 and once to negative post, the voltage immediately dropped to 12.2 volts,Why?

You haven't answered the questions in my last reply.

My ref inputs at Program-Charger-Values are as follows:
gas--13.80
absorption---14.20
float----13.60
equalization---14.20
minutes----0

I noticed that the V2 TB-2-4 (Remote) is not connected to anything should this be connected? If yes to what?
When I connected yesterday to V2 TB-2-8 as per drawing number AT9401262, the volts dropped to 12.2volts.

And what do you measure for those signals on the V2?

all readings taken to tb-1-10 AFTER ABSORBTION

tb-1 tb-2
1-----13.15 1-----0.04
2-----13.17 2-----0.23
3-----4.52 3-----1.50
4-----0.05 4----4.51
5-----0.05 5----0.04
6-----0.03 6----0.04
7-----12.83 7----4.06
8-----13.19 8----0.04
9-----3.11 9----11.31

There are no voltages on any of those pins that would be what is expected for Vref or Iref.

Measure the corresponding pins at the Emon - just the Vref and Iref pins.
