4-10. ELECTRICAL SYSTEM (CONT)
CHECK WIRING HARNESS CONTINUITY
a. Install all lamps in lights (para. 4-11 and 4-12).
b. Check for continuity between each light lead wire and the chassis. If there
is an open circuit, first check lamp. If lamp is defective, replace it. If
there is still an open circuit, repair lead wire or replace light.
c. Connect all wire connectors at lights.
d. Check for continuity between wiring harness connector pins J1-C, J, E, F, A,
B and pin D (ground). Each circuit should indicate continuity. If not, there
is a broken wire and wiring must be repaired or replaced.
CHECK INTERVEHICULAR CABLE CONTINUITY
Check for continuity between individual connector pins and socket on opposite ends
of cable at terminals J1-C, J, E, F, A, and B. Each circuit should indicate
continuity. If any circuit is open, replace cable. At each end of cable, check for
open circuit between any two pins. If short circuit is found, replace cable.
