Problems with Renogy 20amp DC-DC Charger.
One question Craig if you are still monitoring, Why isn't the fuse panel ground the same ground as my battery ? I have the DC-DC hooked up to the battery pos and neg, and my D+ switch connected to one of the open fuse panel slots that runs from ignition. The fuse panel has a grounding bar, so I ran a switch as suggested with the neg to the fuse neg bar. If I run the D+ switch neg right to the battery no problem, but if I run to the fuse panel ground no bueno. Thoughts?
