Both of these species are not common in North Dakota and were found to have tongues more than twice the length of the orchid spurs. This means that they could reach deep into the nectar-filled sacs from farther distances, without pollinating the plant. Researchers also captured eight bumble bee species.
Ignition coil resistance tests are used on the secondary aspects of the ignition coil. These tests should be performed with caution because the circuits of the secondary part of the ignition can have very high voltage. These tests should only be performed if there was inconclusive evidence in any of the primary tests.
1 With an appropriate tool, pierce the wire (circuit) of the ignition coil's connector labeled with the number 1 in the photos in the image viewer. 2  This is the wire that feeds the Switching Signal to the individual ignition coil that fires cylinders 3 and 4. 3  Attach the probe-end of your Test Light to that tool.
