R/C Tech Forums - ipc v7.1 problems

i have a losi xx-t. i had it for a while and i just decided to try and get it running again. its the adam drake edition so it's all race ready (well it was back then). i hooked up a battery to it today and the ESC (ipc v7.1) turned on LED's functiond but when i hit the throttle it didnt move. it was green when i hit the throttle and went blank when i let off, not sure if thats normal. would you say the esc is bad? i really want to get this car going and i hope its not fried or anything. if anyone can give me some input that would be great, thanks
