(1) Main Switch
Preparation
1. Remove the meter panel and the main switch connectors after
turning the main switch off.
2. Perform the following checking.
(1) Main Switch
Connector Voltage
1. Measure the voltage across the connector B terminal and
chassis.
2. If the voltage differs from the battery voltage (11 to 14 V), the
wiring harness is faulty.
