H O W TO TROUBLESHOOT
The following steps tell you how to troubleshoot. A diagram of these steps is on page 1-3.
Do a visual check and list any faults on DA Form 2404 before making repairs. See Vol II,
If you see any faults that may affect the checkout procedure, fix them now. This does not
mean small things like painting scratches.
Do the checkout procedure in Vol I, Chap 2 from the beginning until you find a fault
When a fault symptom is found, go to the chapter noted and follow the maintenance
procedure given there. If you already know the fault symptom, look at the fault symptom
index in Chapter 3 of this volume. This will also tell you what to do.
After the bad part has been repaired or replaced, do the checkout procedure in Chapter 2
again. This is to make sure all fault symptoms have been corrected.
If all the faults are now corrected, do the remaining maintenance tasks on DA Form 2404.
The job is over and the good assembly is sent back to service.
If all faults were not corrected after step E, the bad assembly is sent to the depot for repair.
The sample fault isolation procedure (para 1-5) shows you how to use the flow charts in this volume.
