nitro hammer problems

[Sdotterer]

I just got my nitro hammer a few weeks ago and everything went fine. I took it out a week later and put new batteries in the boat because they were low. I turned on the boat and radio but the electronics did not want to work. I tried many different batteries and all kinds of stuff but couldn't get the electronics going. I started the boat and the electronics still didn't work. Please help me!!!!

did you check for broken or damaged wires? proper battery orientation in the holder? if you have a multi-meter you should check the switch to make sure it's operating correctly, if it got wet, it could corrode and cease to function. they're easy and cheap to replace if that is your problem. are the servos twitching at all? could be a number of things. hope you get it working again.

the servos are doing nothing. I turn on the switch and the controller and nothing happens.

sounds like a switch to me. unless the rx got wet, and stayed wet. but usually you'll get some twitching if it is the rx. hook the battery directly to the rx and see what happens. if everything goes back to normal, then the switch is your problem. you can get a new one at the hobby shop for about 5 bucks, sometimes less.

hmmmm...i might be on to something, Ron just posted the exact same thing on your other thread. :D

Hopefully it is the switch - that is cheap and easy to replace. A few more questions if the switch is not the problem:

* Did the boat get wet inside the radio box?
* Are you running in fresh or salt water?
* Did you completely dry out the boat after the last day's running?
* Are the plugs for the switch and the servos plugged into the correct ports in the receiver?
* Did you ever put the new batteries into the battery holder backwards?

The best answer to the problem would be a bad switch. The worst would be that you left the receiver and servos soaking in salt water for two weeks.... :(

I have sold a few Hammer's to customers who did not realize that they got them wet. I found that very little water in the radio box will 'wick' up into the servos, as their bottoms are very close to the box bottom. You need to check all of the electronics out. You can test out the switch first by plugging the battery holder directly into the receiver batt slot (make sure the wire colors match up). If you still get 'zip', then take the receiver and servos out and open their cases up. If you have a compressed air source, blown them out, and then spray the guts with WD40 and let them air dry for a day. Sometimes, if the corrosion isn't too bad, the servos will come back to life. If you still get no response, if you have an extra servo, plug it in and try it all again. Hopefully only the servos (or switch) are affected. If this sounds too difficult to do, take the boat to your local hobby shop and they should be able to check everything out. If you do need servos, the Futaba 3003 is a basic replacement and should not cost you more that $10-$15ea. RC

*NO water in the radio box that i can remember
*fresh water
*plugged in the correct ports
*never put the batteries in backwards; but what would that do?

[BoatDoc]

putting the batteries in backwards makes all the little bits inside the reciever puke because they prefer their polarity the other way. seriously though, lots of the electronics are meant to have electricity flow a certain direction...if you switch it, you'll damage those parts. i'm not going to give a lengthy technical explanation, as i don't have the background to do so. i just know the basics.
