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.
It's best to check the coil's primary resistance with an Ohmmeter (a digital multi meter in the 200 â¦ mode). Install a 1.4 â¦ or so external ballast resistor (HS14BR) between the ignition switch (+12-Volt power source) and the coil's + terminal, if the coil's primary resistance is questionable or borderline.t's best to check the coil's primary resistance with an Ohmmeter (a digital multi meter in the 200 â¦ mode).
