1.2 Inspecting the Starter System

Output voltage
∗
This should be tested approximately 10 minutes after stopping (because the voltage
immediately after stopping will be the same as while running).
1. Using a tester, check if the output voltage requirements specified above are met.
2. If the voltage is significantly different than specified above, stop the system using the
onboard checker and wait for 5 minutes; then, with the power OFF, check the harness for
continuity and the junction connectors for contact failure using a tester.
3. If the harness and connectors are OK, then check each component.
[Note] Perform voltage checks by applying a tester to the back face of each connector, rather
than unplugging the connector.
„
Fuses on the harness
Inspect the fuses on the harness to make sure they are not blown.
„
Inspecting the starter transformer
Inspect the transformer by measuring the resistance between its terminals.
