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.
To perform a standard ignition coil primary resistance test, the ignition should be off in the car. Once the two low voltage coil terminals are disconnected, the resistance should remain between 0.3 and 1 ohms. A switching test uses a 12 VDC test lamp. A small straight pin should be inserted into the wire that runs the negative coil to the TFI module. The pin can then be connected to the lamp.
Stalling of Vehicle. One ignition coil symptom that previews what occurs when the coil fails totally is a stalling engine. Engine failure will result when the coil totally fails. If the ignition coil is not working, the existing spark plug is uneven, which causes uneven firing of the pistons.
