Step 2.
If the CHRG/BAT FAULT lamp was on (step 1.h) and all voltage
measurements (steps 1.i and 1.j). were in limits, the battery charger
is functioning properly. Reconnect connector P2 and cable P32A6 to
battery charger.
Step 3.
This step is applicable if CHRG/BAT fault lamp was off (step 1.h). and
all 50 amp output voltages (step 1.i) were in limits.
a. Connect battery and set MASTER SWITCH to ON. If CHRG/BAT
FAULT light does not light, see malfuntion 2. If light comes
on, do step b.
Set MASTER SWITCH to OFF and disconnect battery. Check diode
b.
TB3-CR4 (malfunction 82). Replace diode if defective. If
diode tests good, do step c.
c. Disconnect harness connector P1 from battery charger. Check
for continuity between P1-G and TB3-8 ANODE (FO-1). If no
continuity, replace wire P29A20. If continuity, replace
battery charger (paragraph 4-28).
Step 4.
This step is applicable if one or more of the 50 amp output voltages
(step 1.i) and the 20 amp output voltage (step 1.j). were out of
limits.
a. Disconnect battery.
Check for continuity between battery charger J4- terminal and
b.
dc ground stud. If no continuity, replace cable P21B2N. If
continuity, replace battery charger (paragraph 4-28).
Step 5.
This step is applicable if all 50 amp output voltages (step 1.i). were
0, and the 20 amp output voltage (step 1.j). was present.
a. Disconnect battery.
b.
Check circuit breaker 2CB1 on upper electrical tray. If
breaker is open, do step c. If breaker is closed, go to
step d.
