- Start engine and run at 2000 RPM. Measure battery voltage and observe charge warning indicator. If battery voltage increases to greater than 15.5 volts or indicator flickers, replace generator. See GENERATOR under REMOVAL & INSTALLATION. Check system operation. If battery voltage is 15.5 volts or less and indicator does not flicker, repair Yellow/White wire and check system operation.
