Vacuum Switch E

  1. Disconnect vacuum hose to vacuum switch E and connect a hand vacuum pump to hose. Apply vacuum to switch. Check for voltage at Brown/Black wire (1500 HF Calif.) of vacuum switch E.
  2. Voltage should be available when vacuum below 2.2 in. Hg (1500 HF Calif.) is applied. If there is no voltage, replace vacuum switch A and retest.
