The stabilizer stabilizes the operating voltage for powering devices.
Remove the dashboard kit, leaving the connectors connected.
Connect ground to battery.
Connect a voltmeter between input -1- and ground. Required value: approximately battery voltage (12 Volt). Otherwise, find an open circuit using the electrical diagram.
Check the output voltage by connecting a voltmeter between output -3- and ground -2-. Should be: 9.75-10.25 volts, otherwise replace the voltage regulator.
