WebA grounding design starts with a site analysis, collection of geological data, and soil resistivity of the area. Typically, the site engineer or equipment manufacturers specify a resistance-to-ground number. The National Electric Code (NEC) states that the resistance-to-ground shall not exceed 25 ohms for a single electrode. WebA common secondary resistance may range between 6,000 to 12,000 Ohms. If your reading is below specification, most likely the secondary winding is shorted. Replace the ignition coil. If your reading indicates infinite resistance, there's an electrical open in the winding. Replace the ignition coil. dairy supply and demand https://earnwithpam.com
