I have a similar issue after change my T-15 Cell (old cell had a melt down). After the replacement of the cell the system came up normally and all looked good until the power light started to blink and finally went out after 3-5 minutes leaving only the generating light on. The power light will stay off even after a quick power cycle but the generating light will come back on. If I turn the system off for an extended period of time (let everything cool down) the system will once again power on normally with both the power and generating lights coming on after the flow light turns off but again the power light will go out after 3-5 minutes leaving only the generating light on.
I have checked the diagnostic display voltage and current per the manual when the system is in this state and they are within the specifications given but again only the generating light is on. So I'm not sure if the system is generating or not. I have changed the fuse and the current limiter as the posts here show them as high fail items but neither fixed the failure mode I'm having. Before I buy a new board has anyone seen this failure mode before and where you able to fix it? Thanks in advance for any help you can provide.
