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.
Tips. 1  If you do not see sparks, check the output on a voltage/ohm meter. 2  The primary coil should produce readings between 0.7 and 1.7 ohms. 3  Aftermarket ignition coils are built to different specifications and tolerances that can affect the performance of the ignition system.ethod 2 of 2: Performing an Ignition Coil Resistance Test (Bench Test). 1. Remove the ignition coil from the vehicle. The test above isn't the only way to determine whether the ignition coil in your vehicle is functioning as it should.
