Hey Guys Ok so i dont really know how to explain what this truck is doing So please look at the vid first !!! this is a 2010 Peterbilt 387 ISX engine with an eaton ultra transmission . It has been giving me all kinds of trouble with electronics and gauges lately not sure what is going on , it has a 2 month old alternator , brand new batteries , have been looking for loose wires all over , double check the grounds and it still randomly does this. Any ideas ??
