if you havent charged the liths for a wile they may have droped below the safe voltage and therefore will no longer work

try some other batteries , if they work its your liths , if they dont it could be the fets or a looose wire

Do you have a multimeter? That would be the easiest way to work out where power is being lost... otherwise your liths might just be totally dead and no longer hold a charge or you might have a loose wire...

could be a circuit board issue, even the little bit of water that you ran on ur tires could have shorted something out. check ur servo wires and battery connectors.

Its a small device, you put 2 small prongs on the battery ( the negative side and the positive side), and then it will tell you a reading in volts. Something just like this, you can get the analog one or the digital one, http://www.radioshack.com/product/in...ductId=2999093 . They sell them at Radio Shack, http://www.radioshack.com/family/ind...goryId=2032305 .

Next time you turn it on, and go foward, hold a volt meter on the motor,hold down the throttle (its prolly easier to tape it), make sure its taped on full throttle, if it gets one reading, then its not your circuit board its your motor. If it gets different kinds of reading at the same time, then its either your FET's, or your batteries. Thats the best help I can give you, thats just my experince, from what I've learned from blowing FET's, blowing motors, never had liths though, but over powering the motor will basicly ruin it. If you can still turn very good for a long period of time, but the motor doesnt move like it should, then it would either have to be the motor itself or your motor FET.

ok now im sure my liths are chaged. they work. i found out that the the motor was missing a brush. i think that was the problem. idk how but yea. now i dont get a good connection. this is madness!!!! anyone know how to fix it?? i replaced the transmitter. and crystal. nothing. it only works it wants to. when i first turned it onit didnt have anything i moved further away and i got a connection for about a second. then i tried it from all points of my room.

replace both brushes at the same time.
and when you put the armatures back into the motor, be sure you hold the brushes apart and then slide the armature into the endbell before releasing the brushes so that your communator doesn't break your newly installed brushes.

You might have let the atenna touch the negative or postive side of the motor wires, because that can fry your range. Its best to just replace the motor that you have no with one that doesnt need FET's upgrade, but will withstand the power from the liths.

Evo or Gen 1 ? Assuming Evo, you probably have fried the range. About how far are you getting with it ? You'll need to replace the inductors with some other ones. If for Gen 1, then get the range repair kit found on AM.
