I'm confused over "grounds".
I know just enough about electricity to hurt myself. That said, I read a lot of posts about loose grounds. With the DC aspect of the RV is the ground the return to the negative side of the battery? That is the chassis, metal framework, etc.?
On the AC side what is ground? It's obviously not a long copper rod stuck in the ground.
Finally, if I feel the need to go looking for loose grounds how do I do that without destroying my unit? We own a Lacrosse 328RES. I assume all my grounding connections are behind walls or covered up by the cover on the bottom of the trailer.
Thanks for any words of wisdom.
