HEY GUYS!!!! ok i was putting the electronics into my digger well i got em all it but i noticed that the wheels were really hard to spin so i kept spinning em to try and free em up it didt work so i thought it was just the resistance of the motors magnets so i pluged all the stuff together to make sure it all worked properly first i checked the steering then i went to tap the gas and i noticed that the armature arked to the cap. !!!!!!! i was like ***????? so i went to show my brother and this time the motor started sparking like crazy and the cap. wire started glowing red hot!!!!! then i turned it off and spun the motor again to see if it was still stuck well it was hard to turn for about half a revolution then it got easy so i pluged the batt. back in and tapped the gas and it worked just fine!! man it was wierd do u have any idea what the heck happend?? all i know was it was cool! heh BTW it is a stock 540 motor.

Your cap wire probably was shorting the positive and negative side of the endbell. You have to be careful with capacitor wires !

Good call Jeep. Thats about the only posibility. I have always wondered why it doesn't happen more often. The reason we get away with all the bare wires so close to each other is the relatively low voltage that these things run on. If it were even at normal 120v house current there would be fires all the time!

On the topic of capacitors, The Team Orion motor I got (coming in today) emntions it uses snap-in caps. Are these normal capacitors that snap into the motor endbell or are they special capacitors housed in a special case that can snap in? Weird... guess I'll find out in a couple hours.

Actually Railman, the voltage isn't going to cause the fire, it is the current that you have to be careful with. Some of these batteries can draw scary amounts of current.
