I'm sure it's out of warranty and I went to college for electronics many moons ago. I'll take my chances. Besides, repairing toys is part of the fun.

Good morning all, I am having an issue with the speed controller. Just now i am unable to switch directions. The red light will dim and the engine *might* slowly move a millimeter then stop. If I switch directions the light stays bright and the engine moves normal. If I reverse the connecter the engine will do the exact same thing, but the direction is reversed. This is happening with both engines I have tried. I can't find my multimeter to test the voltage, but assume it's the speed controller. 

Has anyone else had this issue? I'm handy with a soldering iron and can replace the defective part. Too bad I can't find my multimeter...
Thanks for any help.
