Just a brief update on this project. The reliability of this “fix” has gone down substantially. I’m still thinking this is related to the temperatures since fall started and now winter has come, it takes longer and longer for the charging to kick in. Now it seems like 15+ minutes in my ride before it starts to charge. Likewise though if it’s a sunny day and not too cold and the temps in the car are fairly warm, it seems to substantially improve the charging. No idea if this is really the cause but just seems to be pretty consistent. Will see what happens as Spring approaches.
