1-3. HOW TO TROUBLESHOOT

The following steps tell you how to troubleshoot. A diagram of these steps is on page 1-3.

(A) Do a visual check and list any faults on DA Form 2404 before making repairs. See Vol II, Chap 3 for what to check

for.

(B) If you see any faults that may affect the checkout procedure, fix them now. This does not mean small things like

painting scratches.

(D) 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.

(E) After the fault symptom has been corrected, do the checkout procedure in Chapter 2 again. This is to make sure that

all fault symptoms have been corrected.

(F) If all fault symptoms are now corrected, do the maintenance tasks on DA Form 2404.

(G) Do the final inspection given in Vol II, Chap 5.

(H) The job is over and the good assembly is sent back to service.

(I)

If all fault symptoms were not corrected after step E, the bad assembly is sent back to the depot for repair.

The sample fault isolation procedure (para 1-5) shows you how to use the flow charts in this volume.
