Figure 8: 12v DC motors sealed with electrical tape

1. (Very Important) Make sure the negative and/or positive terminals are marked on each motor (see previous step) so that you can tell them apart after covering the motor in tape. Refer to the Tether Wire Color Code Guide to assist you.
2. Completely wrap each motor with electrical tape to seal the holes. It may be easiest to cover the ends of the motor first and then wrap around the sides. Leave the motor shaft and the electrical terminals outside the tape. Make sure ALL holes are sealed.
