I have tried adjusting the DC scaling number with no change to behaviour, but I have not yet tried changing the output charge value. I can try that in the near future.
I only have one of those chargers remaining, but it seems odd that mine and Bulletbug's chargers are all broken in the same way.
If I can record CAN captures of my unit's behaviour, would that be of help for further diagnosis? At least then we can see if it's a common error among certain versions of the Gen2 charger.
I do also have a working unit that I've been using for a while. When I swap the open source boards around the working charger stays working, and the non-working one stays non-working.

Thanks so much for all the time you've spent with me today. Hopefully we can keep things out of the trash pile that don't belong there...and increase confidence with people that they can make a working charger without it being what appears to be such a hit or miss gamble.
A note that I've mentioned earlier but since I think we're looking for the peculiar rock to turn over, I'll mention it again. I think this is a stretch but I'll just have to risk looking like I don't know what I'm doing (most of this is all very new to me)
My board does not currently have the c30 capacitor which sits next to the boards reset switch. The board mfg. company told me they kept oxidizing on them when they attempted to install so after asking around on the forum it sounded like it was an optional component that was only called for in "harsh" environments which I'm guessing means either stray voltage noisey or radio signal noisey. My battery cables are not shielded if that has an impact in this discussion.
Bottom line, I'm ordering several different brands of this capacitor and will get it put in place. I'm guessing (but will research) that shielding gas like what is used in a mig welder may prevent oxidation. So I'm considering removing my mig wire and running the gas over the c30 location when i solder it.
