Here's what I've been able to gather.
1. Volts at the large cables coming out of the converter is 11.55V
2. The green light is flashing which according to table means bulk charging.
3. I am having trouble getting the fuses out of the converter. I put probes across the back and it seems like I am getting 5.5V, but can't see well to make
4. After being hooked up a little bit, the refrigerator went to code "C" again.
5. I noticed the large blk wire running from the converter to the 12V buss panel connects with 2 blk wires going into the buss panel. The OP has used a large wire nut for this connection.
After fooling around with these wires, now the frig is back to normal ac code lit.
Currently the lights are brite and the frig is normal. Maybe this large wire nut is not making a good connection and then was running 12V stuff off the battery instead of the converter?
Here's some pics.
This is the converter I have
Here are 2 fuses on the back of the converter that I am having trouble getting out. Tried once with needle nose pliers, but they are tight.
Do they pull straight out, no locking mechanism?
Here are the 2 large wires coming out of the converter where I am measuring 11.55V. I'll check again after fooling with wire nut.
It is still 11.55V and 11.55V at the battery terminals
Here is the 1 lg black feed coming from converter combined with 2 lg black wires to distribution/buss panel. Connection made with large wire nut.
I am going to watch this situation for the afternoon and see if maybe this wire nut connection is iffy. Currently everything seems normal.
Please feel free to digest the data and pictures I've attached and let me know what you think.
In the meantime, I am going to stop by the store and get some distilled water to top off battery cells.
