Hi All,

I've got a open neutral line in a circuit.

The VOM can read the voltage across the bare copper ground and the hot
lead but it does not register any voltage between the insulated neutral
and the hot lead.

What's the best way to troubleshoot this?

Start at the breaker and proceed down the line, follow where it goes,
open any boxes along the way. The most likely source of a problem is
where there is a connection, eg wire coming out of a back-stabbed
receptacle, etc.
