battery ground

hey folks, can anyone give me some ideas on where is the best place to ground the battery? I've read some things that say bare metal is good, but others say there is a specific place. Right now we have it grounded to the generator stand since its welded to the frame.

Not being familiar with busses I'm going to have to ask the basics. Is there not a threaded hole near the battery? My thought would be that VW would have installed a mounting point for the ground wire. Mabey some part of the frame nearby that bolted together? Yes, bare metal is best.

thanks for the info, I sent the link to my boyfriend. The pictures they had don't look like our engine compartment, but I think our ground is ok. The generator stand had a hole in the middle of its upright support so that is what we bolted the ground to.

HMMMMM I thought there were two,
1) Battery to chassis/frame
and
2) frame to transmission (which is bolted to the engine)

Correct, there should be two. By grounding to the generator and having ground on the trans, they are doing the same. The only downfall that I could think of is the radio might have a high pitch noise when the engine is on and if the trans to frame ground fails, nothing will work.
