Good afternoon! I hope someone can point me in the right direction because I am at my wits end.
I have a Case 580 Super L, 4x4, that will not start. It does absolutely nothing when you turn the ignition switch to "ON", and will not crank.
The battery is good, I even hooked up jumper cables to a second battery and I still had no response at all. No lights/horn/instruments/anything.
When I check for power on the ignition switch I have 12V, but when I turn the key to "ON" the voltage drops to 0V. Turn the key back off, 12V returns to the power wire on the ignition switch.
I checked the function of the switch with a multimeter after disconnecting it and it seems to be operating ok. I also tried jumpering the 12V wire on the ignition switch to the wire that powers the accessories, and to the wire that should make it crank, all to no avail.
I pulled, cleaned, and added dielectric grease to all the fuses and relay posts. I swapped around relays. Still no power to anything despite it being at the starter post, ignition switch, and the power block below the relays/fuses.
I cleaned out all the nooks and crannies in the engine bay and under the floor plate to look for broken/chewed through wires...nothing seemed out of the ordinary although something certainly had been living in the space just behind the motor compartment, above the transmission. Tons of grass and twigs in there but all looked fine after cleaning. I tried to check the neutral safety switches but I cannot seem to find any information on where they are. Plus I would assume if a safety switch was bad I could still turn on the lights and such.
Lastly, a bit of information on the unit. About a year ago it exhibited these same symptoms, but then the issue resolved itself after a few minutes. It has been fine ever since...until yesterday. I was loading the backhoe on a trailer to move it, started fine, ran fine, loaded fine. I turned it off. I then realized I needed to reposition the boom a bit, so I went to crank it over again and it cranked super slow as if the battery was almost drained, then nothing. No noises, smells, sparks, etc. All of a sudden nothing worked. Further turning of the key in the ignition did nothing.
So now the backhoe is sitting on a trailer, can't take it off, can't get it to run. Has anyone ever had something like this happen? I'm sure it's something simple and electrical, but I cannot find it and it doesn't help that there is virtually no information on this unit online. I cannot find a wiring diagram to save my life! So any help would be greatly appreciated. I have got to get this thing moving.
