Attempted to start tractor. Needle on right side gauge moved when putting ignition in warmup position (needle did not move on left gauge). When putting ignition in start position, only a click sound could be heard on left side of dash. Tried a couple more times with same result. When I turned ignition to off position, a cracking noise occurred for about 3-5 seconds ..sounded like the noise was from the left side of the dash. Lights worked before...now there is no lights; also, nothing happens when I turn ignition key now. There are two electrical modules under the dash on left side...I replaced the outside module but with same results. Any ideas what may be causing problem?
