Test 7 - Power Supplies

Test LB87-8 (LB87-7) for short circuit to ground

If not ground, fault is open circuit bulkhead harness.

If ground, test LB86-16 (LB86-16) for short circuit to ground.

If not ground, fault is open circuit bulkhead harness.

If ground, test LB87-1 (LB87-9) for normal battery voltage.

If normal battery voltage exists, test passed.

If battery voltage does not exist, test LB10-6 (LB65-6) for normal battery voltage.

If normal battery voltage exists, fault is open circuit bulkhead harness.

If battery voltage does not exist, fault in fuse, fuse box, or short circuit motor feeds. (Complete test 8 before replacing fuse).


NOTE: Normal battery voltage exists when voltage at test point is within .5V of voltage measured at battery terminals.
