I went to drive my truck today. i got it started and drove for about 30 seconds. then my throttle stopped working and steering wouldnt work no more either. i changed my batteries and went back out. my throttle worked again but no steering. couldnt figure out why it did that, then my throttle stopped working again. I'm new to my truck so i dont know much, but i bought all new batteries and still nothing. any help would be appriciated.
