HELP needed with HALO

I can't seem to get to Pulse Generator #2.
I take a Banshee to the cave entrance and the voice says "capture a
banshee and take out the Pulse Generator #2 before entering the cave".
Also it says to "follow the Navagation markers".
When I get in the Banshee I fly it to three different locations but
the Navagation marker never shows on the screen.

Any ideas?

Thanks,
Terry

It's been a while. IRC, its the highest platform in the outer wall of that
circular canyon.
