Ground Circuits
- Using a DVOM, check for continuity to ground on ECA terminals No. 40 and 60. Resistance should be zero ohms. If not, repair open to ground.
- Using a voltmeter, touch negative lead of voltmeter to a good ground. Touch positive lead of voltmeter to each ground terminal. With vehicle running, the voltmeter should indicate less than one volt. If voltmeter reading is greater than one volt, check for open, corrosion or loose connection on ground lead.
