Having electrical problems and cant seem to fix it. Machine starts and runs fine, However, Parking brake is locked and all the guages are not responding. When you put the seat belt on the lights flicker and thats it. The machine is just "locked up", wont move and hydrolics are also locked. I have checked all fuzes and they are fine. I have checked relay switches and also fine. There is a new alternator and battery. I also replaced the relay sensor inside the headlight light housing, still not working. Any thoughts would be more than helpfull. Thanks Greg
