I have a 2004 S185 Bobcat. I bought it used and have used it for about 2 years, all light duty. It has about 1700 hours on it and lots of rust. I now have an electrical problem that started about a month ago with a warning that the glow plugs were not working, a warning light and an error code (21-03). The plugs were not working because the engine was difficult to start. The temperature was about 50º. I started checking the fuses and relays located under the front of the seat. The fuses were OK and those contacts looked good then cleaned the relay contacts. Now there is no power to the starter switch, no beep or hour meter, nothing. Removing the fuses and relays probably caused the loss of power to the switch. I checked for power at the relay sockets (where pin 30 goes in) and that was OK, power at all six relays. Battery is good. I cleaned the ground connection behind the cab located about head high on the left side. There were two ground wires bolted to the frame. The ignition switch wiring harness plugs into the back of the right instrument panel. So the power to the ignition switch goes through the right instrument panel from that wire loom. The ignition switch connector plug is difficult to remove. I will remove that switch plug and check to see if there is power there, which I doubt there is. I will provide a link to photo bucket of the wiring schematic. This schematic does not show the ignition switch with seem rather odd to me. It shows the left and right panels, controller and the fuse/relay center. http://s12.photobucket.com/user/lanceh5/library/Bobcat This is a slow process for me.
