12. Disconnect connector 6a from connector 5b and con-
nector 7a from connector 5c. See diagram 2.
13. Measure voltage across pin 1 and pin 2 on connector 6a,
then measure voltage across connectors 6b and 6c. See
figure 16.
— If the multimeter indicates the same voltage for both
tests, then go to the next step.
— If the multimeter does not indicate the same voltage for
both tests, then replace the rear battery harness (6) and
retest the system.
14. Measure voltage across pin 1 and pin 2 on connector 7a,
then measure voltage across connectors 7b and 7c. See
figure 17.
— If the multimeter indicates the same voltage for both
tests, then go to the next step.
— If the multimeter does not indicate the same voltage for
both tests, then replace the front battery harness (7) and
retest the system.
15. Measure resistance across the two terminals of the cir-
cuit breaker (13). See figure 11.
— If the multimeter indicates less than 1 ohm, then replace
the power interface harness (5) and retest the system.
— If the multimeter indicates greater than 1 ohm, then
replace the circuit breaker (13) and retest the system.
From step 11
16. Unplug connector 3a from connector 2a. See diagram 2.
17. Measure resistance from pin 1 on connector 2a to pin 1
on connector 2d and measure resistance from pin 4 on
connector 2a to pin 2 on connector 2d. See figure 18.
— If the multimeter indicates less than 1 ohm for both
tests, then go to the next step.
— If the multimeter indicates greater than 1 ohm for either
test, then replace the Dynamic power module (2) and
retest the system.
18. Disconnect connector 3b from connector 4a. See diagram 2.
19. Measure resistance from pin 2 on connector 3a to pin 2 on connector 3b and pin 3 on connector 3a to pin 3 on
connector 3b. See figure 19.
— If the multimeter indicates greater than 1 ohm for either test, then replace the Dynamic bus cable extension (3) and
retest the system.
— If the multimeter indicates less than 1 ohm for both tests, then go to the next step.
