DUN RUNNIN!
Ok this started happening to me last night. I was driving along on the highway and hit a weird bump. My truck made a noise and then when I came to a stop at the redlight my speedo gauge was jumping from 13mph to 20mph while the vehicle was sitting still. Then this morning I tried to start up the ranger and it was dead. I jumped it off and drove a while and now it wont start at all. Any ideas? my thought is the voltage regulator on the alternator is out. What do u guys think?
