D2 Dirtinator resistor exploded
Hello everyone!
I received a rc10 t2 it had a modified motor with it and looked new. It did not have the ground and power connected yet so I soldered them on and installed motor. It was being powered by a Traxxas 7.4 2200 mah battery along with a Traxxas xl5 ESC. The truck was very fast and ran flawless through 2 battery charges but on third charge it slowed to a stop. Steering worked fine and battery was OK. My soldering skills are not great yet so I reconnected the leads for power and ground. Powered up the truck and drove about 3 feet and the resistor exploded. Im not up to par on my electrical stuff either so I may be incorrect but by looking at other motors I believe resistor is correct. It is long and cylindrical. My question is does this mean that there is a internal issue with this modified motor or just possibly a bad resistor? Thanks for any help and it's great to be apart of your group!

Brushed motor? Probably the capasitor. I've had them blow up. Sounded like a firecracker. I just put another on and moved on. They have a + and - side so it matters wich way you put them.

I put the motor back in my RC10 T2 and it ran fine then started loosing power. I turned it off batt was hot wires to motor were cool and motor was cool. Batt is a 2200 mah motor is a 13 turn brushed motor Is batt to small?
Check the brushes

Thanks for the reply! At what point do brushes need to be replaced? I have slid them out and they are worn the same amount both sides but being new at all this I'm not sure how much wear is to much. I know there is alot of brush left. Thanks Heath

Also look at the comm, If the brushes are burnt the comm probably is too.
