RE: New to the R/C world - Need motor help!!
I appreciate the help guys. Sometime tommorrow afternoon I'm going to call the company about the warranty issue!

RE: New to the R/C world - Need motor help!!
Thank you for your replies! I'll try to clarify things a bit and let you know what I have checked.... - The bad motor [b]does[/b] spin when you turn the prop by hand, so it is not siezed. - The resistance across the good motor is 0.4 ohm - The resistance across the "bad' motor is also 0.4 ohm - The voltage across the good motor when remote trigger is pressed is right about 7.2 volts - The voltage across the "bad" motor when remote trigger is pressed is 0 volts - Voltage across good motor when remote steering wheel is turned to the left is 7.2 volts - Voltage across "bad" motor when remote steering wheel is turned to the right is 0 volts I opened the speed control box to take a look at the board, but didn't remove the board because all of the input wires are sealed with silicone and I didn't want to take a chance of voiding any possibile warranty! When the steering wheel is turned to the right there is a definite " clicking" coming from one of the two relays on the board. There obviously seems to be a problem getting power to the bad motor since there is no voltage across it, right? But, wouldn't a measurable resistance eliminate the possibility of an open in the circuit? If I remember correctly, an open is equivilant to infinite resistance.... Other than that, I guess I'll have to see if what you guys think, and just have to wait while someone checks on the warranty info. I also have another quick question for the tech guys lol: What is the reason for the small capacitors that are soldered onto the electric motors? I noticed there is three on each motor, and I think other electric motors that I have seen also have the capacitors. Hopefully I don't sound stupid because I'm pretty sure they are capacitors lol. Two of them are brown circles with "104" on them, and the other is a familiar cylindrical cap. That's it!!

New to the R/C world - Need motor help!!
Hey guys, I just got a Water Open PX-16 electric r/c boat ( http://www.wowzzers.com/product_info.php?products_id=135 ) for Christmas from my girlfriends parent's but after about 5 minutes of use, one of the electric motors have stopped working. I opened the top to see what was going on, and there is definitley no movement of the motor or propeller shaft on the one side. When I turn the remote wheel back and forth though, I can here a clicking noise coming from what sounds like a relay inside of the speed control box. Is there anyway diagnose and/or test an electric r/c motor? I am new obvoiusly, and I would like to fix this thing so I can have fun with it again! Any help or pointers would be great. Thanks. Joe
