Ground Circuits

  1. Locate Electronic Control Assembly (ECA) behind right kick panel. Using a DVOM, check for continuity to ground on ECA terminals No. 40 and 60. See Figure . Reading on DVOM should be zero ohms. If reading is not zero ohms, repair open to ground.
  2. Using a voltmeter, touch negative lead of voltmeter to a good ground. Touch positive lead of voltmeter to each ground terminal. With engine running, voltmeter should indicate less than one volt. If reading is one volt or more, check for open, corrosion and loose connection on ground lead.
