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.
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.
