External Fan

  1. Connect tachometer to engine. Start and run engine at 1500 RPM with no electrical load (foot off brake and doors closed). Read voltmeter when voltage stabilizes. This may require waiting a few minutes. Voltage should increase, but not greater than 2.5 volts more than base voltage.
  2. If voltage increases to proper level, proceed to LOAD TEST. If voltage increases beyond proper level, proceed to HIGH VOLTAGE TEST. If there is no voltage increase, proceed to LOW VOLTAGE TEST.
