Engine will start fine. However, tractor will not move. Transmission will go in each range but not in any gears within the range. Hydraulics work fine. Also the battery warning light is on as well as the three lights: stop, yellow caution and blue caution all blink. Plus the tach does not work. This is an intermittent thing and does not happen each time I try to start. If it does start and no lights blink, it will run fine. Anyone had this problem or know what the problem is.
