This is watching the retract and extension cycles of a Piper Comanche while monitoring the current draw using a DC clamp-type ammeter. It should be noted that the higher current drain at the end of the retract cycle is due to the gear being pulled tight against the bumper strips in the wheel wells - a normal condition. If your current drain is over the limit of 17.5 amps, find out why.
hmmm, i should share some video's of my comanche.

Great video Matt. Since there are numerous wires in and around the gear motor, maybe in your next video you can point out which of these wires (color wise)is the correct wire to put the amp clamp on. Or let people know that they can also put it on the main battery cable and get the same result minus any other amperage reading that happens to be on at the time such as cooling fans, gyro etc.. This video is great because owners can direct any of their IA's or A&P's to watch it.
