Sea Perch Troubleshooting:

Problem:  The motor connected to the orange and orange white wires are not working when connected to the circuit board.

Solution:  To determine that the problem is not in the film canister or the motor itself, cut the orange and orange/white wire. Then take off about ½ inch of insulation from each end.  Attach one wire to the red side of the battery and the other to the black side (as you would if you were using alligator clips).   If the motor moves, the problem is in the cat-5 cable.  If the cat-5 clip has already been crimped, a new cat-5 cable must be used and that process must be repeated.  If the motor does not move, the problem is in the film canister.  Cut the orange and orange white wires near the broken film canister.  Using a new film canister and motor, repeat the process of coving the motor with tape and filing the film canister with wax.           

NOTE: This solution should work for any colored cable.

Problem:  The cat-5 cable does not “click” into the circuit board.

Solution: Using a crimp tool, which is a hand-held tool designed for cat-5 cables, place the cat-5 cable in the designated spot and squeeze the crimp tool multiple times to ensure that the golden rods on the top of the cat-5 table are completely pressed down.  The process can also be completed by using a narrow flat headed screwdriver and pressing down each of the golden pins individually.  

Problem:  When testing the circuit board none of the motors work. 

Solution: Test the cat-5 cable in a known working circuit board to determine that the cat-5 cable is not the problem.  Next check the solder and make sure that no connections are touching.  Then, check to make sure that the fuse is the right size and positioned correctly.  Lastly, using a multimeter, check to see that each of the connections have amps going though them.  If the above steps fail, re-do the construction of the circuit board with new materials. 

Problem: Accidently cut a wire.

Solution: First, strip about ½ inch off the insulation off each end. Then, solder the connection together.  Next, use electrical tape to tape the connection.   Lastly, use Butyl Rubber Tape (monkey dung) to cover the electrical tape so this part of the wire can go in the water. 

Problem: Previously, switches were working fine, yet suddenly they stopped working.

Solution: Go though every wire connection on the bottom of each switch and make sure the solder is not touching another connection and causing a short circuit.

Problem: The propellers don’t spin, but you can hear the motors vibrating.

Solution:  Peel the glue surrounding the connection between the propeller shaft and the film canister.   Continue doing this until you can spin the propeller shaft with your fingers.

Problem: The propeller attached to the green and green white cord spins the wrong way.    

Solution: Cut the green and green white wires. Then take off about ½ inch of insulation from each of the 4 ends.  Attach the green wire to the corresponding green white wire and vice-versa (this should form an X).  Solder, electrical tape and Rubber Tape (monkey dung) the connection.      

NOTE: This solution should work for any colored cable.

Problem: The PVC pipe separate in the water

Solution:  Using epoxy glue, if you are unfamiliar with using epoxy glue refer to the construction manual, coat ½ inch of the inner PVC pipe with the glue.  Connect the PVC as usual.  It is fine if the glue dries on the outside of the PVC pipe.  Let set for 1 hour.
