[Tex/LaTex] How to locate overfull \hbox too wide error code

warnings

I am getting many overfull \hbox(4 pt) too wide warnings in my code. But when I click on the warning, it points to a the first line of the main tex file which is a comment. And there are many such warnings which are pointing to the same comment. Since it is not pointing to the line that has the warning, I am not able to edit the code. Could you guys please provide your inputs on this?

The document class command is as follow:-

\documentclass[SectionMethod, ListStyleI]{TAMUthesis}

The log file description for one of the warnings is:-

[]|
  \hbox(0.0+0.0)x430.0074, glue set - 1.0
  .\glue 3.0 plus 1.5 minus 1.0
.\glue 3.0 plus 1.5 minus 1.0
.\vbox(0.0+0.0)x430.0074
..\hbox(0.0+0.0)x430.0074

..\rule(0.0+0.0)x430.0074
..\glue 0.0
.\rule(*+*)x5.0

The sample code is :-

\documentclass{article}

\begin{document}
\section{Subheading requirements}
This is the second-order subheadings in this  document.\\


\begin{itemize}
\item Vertical spacing above and below each subheading needs to be consistent for each
level

\item Vertical spacing within a subheading with more than one line needs to be the same

\end{itemize}

First-order subheadings, which are section in this  document, must be     included in the Table of Contents, which is implemented in this TAMUthesis.\\



 \subsection{Test Subsection In This Chapter}
A chirp is a signal whose frequency increases  or decreases with time.

\begin{equation}\label{Equ. 3.1}
f(t)=f_0+k\cdot t
\end{equation}


$f_0$  is the starting frequency for sweeping in chirp. Its corresponding time   domain

function for a cosine linear chirp is;

Best Answer

The draft option (understood by all standard classes and so by those based on them, but also by Koma-script classes and memoir) adds a black rectangle next to most overfull \hboxes.

Sometimes, in special situations, this doesn't happen: it can happen in tables, for instance. Nonetheless, the method is usually very effective for visually finding the bad boxes.

So you can try

\documentclass[SectionMethod,ListStyleI,draft]{TAMUthesis}

If this doesn't work because the class doesn't define or inherit the option, adding

\setlength{\overfullrule}{5pt}

to the document preamble should produce the same effect.
