645/333, if you could send me the diagrams I can tell exactly what is happening. I know there is a current shunt in the system to indicate charge current. However, I have a sneaking feeling that IBS may only be using voltage as the indicator of battery condition when it should be a volt/amp ratio vs time. A circuit diagram will show this.
I might have WDS, not sure. Just got back from my 5000 mile trip and bushed. I'll check in a day or two.
