Grid is fine, was a broken wire at the hatch rubber boot section. I had repaired what I thought was the only break, but it turned out there was another break, hidden in the van body.

I have one of those little jars of conductive paint in my messy parts collection. I Last used it on the grid of my '72 westy, way back in '89. The stuff does work, tedious and tricky painting though.

As in: ohmeter probes touched to the grid a few mm apart show conductivity, but any farther apart than that and no current passes. Since you said "no power AT the grid" it sounds like a different problem though, but if you meant "no power ACROSS the grid" maybe we have the same problem.
