Diesel engines are sometimes difficult to start in the cold season. in Electrical Engineering from the University of Louisiana at Lafayette and holds an Oregon Journeyman Electrical License as well as electrician licenses in Louisiana and Texas. Parts . Move the spark plug to a different location and try again, if a spark does not appear. Coil Tests . This guide uses a 9 volt battery and a digital multimeter to test the functionality of the speakers and the wires. Note: I have used caps for filtering before but never for charging/discharging. Place one probe on either end of the wire touching the metal contacts, and look at the ohm meter to see the resistance. The wire runs from the ‘–‘ on … The ignition coil is good if the tool produces a spark. 3. Hook an ohmmeter test lead to the spark plug terminal of the high-tension lead and another to the lamination stack (ground). Any resistance at all would mean the plug is bad.
