Yes, I believe you may start to see some concerns in the readings you get and the activity of the Intelligent Solenoid. Grounding is key to the long term service of the system. The Intelligent Solenoid (IS) constantly monitors the connections and the grounding of their system. That is it's sole purpose, and it does it to a very high degree. Running a single line between the negative terminals is key to maintaining proper grounding connection and sending the right information back to the IS.
What this system does, in essence, is to add a second battery in parallel to the primary battery, and adds an automated switch to control that connection. By connecting the negative on the secondary to a ground point instead of connecting directly to the primary, you are running this charging system through your vehicle. It is now subjecting it to everything else grounding through your vehicle. Frame grounding is not know to be the best grounding solution either. I understand your logic in what you did. But I would suggest putting in the cable between the negative terminals as the instructions state. It will pay off in the long run.
Cheers,
