PROBLEM SOLVED!! Now, the question is, "What was the problem?" Here's the story that ended with the tractor starting and all the lights operating correctly. I disconnected the fuel line to check for flow. First, I checked at the input to the fuel pump. There was just a trickle. Then I mistakenly disconnected the line from the tank to the filter (I intended to disconnect the output of the filter); anyway the flow was fine and of course I got fuel oil all over myself. Then I thought, "hmmm, maybe the fuel wasn't flowing to the fuel pump because the starter switch was in the off position." There appears to be a fuel cutoff selenoid just after the filter. So I again disconnected the line to the fuel pump, turned the starter switch on and wahlla, the missing clicking (check one of my earliest posts) was back, fuel flowed fine (before there was just a trickle), and all my lights magically turned back on! (Maybe it was the abracadabra I was chanting.) So, all I can figure is that the fuel shutoff selenoid was stuck in the closed position and there must be a relay wired to that circuit which opens so nothing will operate if the selenoid is closed. Does anyone know about this?
