The gear doesn't seem to mater, I've been in 1st though 5th and had it die. But it allways dies just after I shift in to another gear some times it will die shifting from 1 to 2, 2 to 3, and so on. I have tried to get it to die doing the brake stand until the tires end up braking lose and start thoughing rocks all over the place. HeHe. And yes accelerating seems to be when it shuts down. as for the rev i don't have a tac so I really have no clue. How would I check these circuits that you talk about Like I said I have pulled all the black tape and plastic conduit off of all the wires and looked them over very good before puting the tape and stuff back on.
