hey guys, working on a millar cvt with dc/dc generator. car keeps tripping overspeed on generator when going in the down direction. doesn't trip when traveling up. when going down i here the generator winding up as car is accelerating to top speed. Motor field voltage is correct in both directions.
i know that tach on machine can cause similar problems. but i never seen a tach fail in one direction. so my question is, has anyone ever experienced tachometer failure only in one direction?
