I am not that familiar with your charger but if you aren't already check out the Sprinter forum. https://sprinter-source.com/forum/index.php


This thread should get you in the right direction.

If that doesn't help let me know and I will dig deeper when I have a little more time.
Both forums have a lot of helpful contributors.

We have a 2016 Sprinter/2017 house Melbourne. I have the Sprinter dead chassis battery
Issue. Purchased a Trik-l-start and installed it on the solenoid at the house battery. Nothing happened. Should I have hooked it up to the one under the passenger seat?
I'm not very familiar with this site and saw that you have a Melbourne and another Sprinter. Thank you if you can help.
