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.
Symptoms of Faulty Ignition Coils. The ignition coil is the source of the spark that ignites the air-fuel mixture in the engine's combustion chamber. The ignition coil receives a voltage of 12V from the car's battery and multiplies it to a higher voltage level.
