Re: DLink / D-Link resets going over bumps! Thoughts?

If you are loosing something when you run over bumps check these things...
1. lightly tap the red button on the main breaker. Do lights on the robot flicker? Replace main breaker it is defective.
2. Does your cRIO move around? It may be shorting to the frame of the robot when it moves. Some RS770 motors are being delivered with a short to case. If you are using these motors check continuity from each motor terminal to motor case. You may be sending power hits to the Crio.
3. Triple check the power wiring coming from the radio connector on the PD. These are notorious for being improperly terminated. The wires should not pull out when tugged and there should be no visible whiskers that can short the two wires together.
4. Check that the battery terminals on the PD are snug and have a lockwasher under the nut that hold the terminals in place.
5. Check the battery connections by moving all #6 wire with the robot turned on. Flickering indicators are a sign that something is loose.
