I am having a problem with a wire somewhere. Seems to drain the power down when you turn on the ignition, lights very dim. In the process of trying to find the bad wire I noticed that the ground wire and the connection at the frame get hot. Is it normal for the ground to get hot at the connection point on the bike?

Heat means resistance.
Is your ground wire heavy enough, and not insulated by paint? If 6v, is it soldered?
Beware that you may be endangering your generator, even if it is not the cause.

Do you have a fuse in the system?

Demoman, A big yes to Cotten on that , make sure that ground connection is nice and clean, take it apart and sand or file it till you got metal to metal, nice and shiny, then tighten up and if you want seal the connection with vasaline or battery terminal spray, heat is bad.

Indeed, heat is bad !! Use a amp meter to measure the current flowing through the battery. If to high you've got a short somewhere. Disconnect all current users to locate.
