Organizational Troubleshooting (continued)
TEST OR INSPECTION
a. If BATTERY CHG/DISCH indicator does not illuminate, see
If indicator illuminates, do step 2.
Set MASTER SWITCH to OFF and disconnect battery. Test diode TB3-CR5
(FO-1) (malfunction 82).
a. If diode tests good, do step 3.
Disconnect wire from TB3-10 (ANODE). Measure resistance between
TB3-10 (ANODE) and TB3-10 (CATHODE).
a. If resistance is between 80 and 120 ohms, reconnect wire and
go to step 4.
If resistance is not between 80 and 120 ohms, replace
Disconnect main harness connector P5 from control panel connector J5.
Check for continuity of wire P29B20 (J5-20L to 1DS7+), and wire
P29C20 (P5-20R to TB3-10 ANODE).
a. If either wire is open, replace wire and perform operational
If both wires are good, reconnect P5 to J5 and continue with
Disconnect main harness connector P18 from lower tray connector J18.
Check for continuity of wire P33K20 (P18-E and TB3-9 ANODE).
a. If no continuity, replace wire P33K20 and perform opera-
If continuity, do step 6.
