Has anyone checked their GROUNDS lately. http://irv2.infopop.cc/images/juggle.gif http://irv2.infopop.cc/images/smash.gif

Intesting that this should come up. I have been posting in the Winnebago forum asking exactly where the physical grounds are and received no useful replies.

I have found the main ground for the battery on the frame. I found another ground just behind the grill. There is another local ground by the gas heater way in the back. I also found a ground for the dash behind the dash. None of these seem beefy enough to carry return current from the coach. I have cleaned them up and re-tightened them.

Are there more grounds and, if so, where are they?

I looked at the Winnebago wiring diagrams and they treat ground as a concept rather than as a physical reality. Only one, the battery ground, makes any reference to its location.

The problem that I am trouble shooting is a voltage difference between the DVM built into the coach and another DVM at the battery. Underr high loads the difference is almost a volt. This causes my gas heater to not fire as it perceives a low voltage condition.

Someone may have an exact answer however, someware around 2002 Workhorse started welding the ground lugs to the frame. My W22 has welded lugs. Mine still appear clean so I have not backed the nuts off to check these.

Bruce, every 12v device needs a ground return some of the grounds will go to chassis frame others to a buss bar. Some you may find in a compartment such as #6 ground wire to frame support of compartment where your converter may be and another for transfer switch. http://irv2.infopop.cc/images/juggle.gif
