SR200

[David1234]

I have a Case SR200 that just died while I was moving some rock this weekend. It cranks but will not start I thought it had ran out of fuel, and it in-fact did sort of. When you turned the key on you should normally hear the fuel pump kick on. It did not turn on after it died. I appear to have lost power to the fuel pump. I checked power to the pump, NO power to the fuel pump. When I jumped the fuel pump to 12 volts it worked as expected, I still have warning lights on the right side of the roll cage, and key switch works. I removed the cover on the left side behind the cup holder and checked each of the fuses there and had no power to anything there. The boom is down and I can't get it up at this point. Is there another fuse panel or a master fuse somewhere??? I will disconnect the lift cylinders and raise the boom with a loader if needed, so I can roll the cab over to get to the wire harness. Seat switch and lap bar should not make a difference with starting. It will start with the cab tilted. Does someone have a diagram of the fuse panel, for the life of me I can't locate my owners manual. I want to see what fuses are what. Suggestions????

Found the diagram on the back of the cup holder. Re checked for power with batter ground, and found that I did have power to the fuse block, but only up to the main power relay. Swapped main power relay and one of the light relays and was able to get power back to the fuel pump. Allowed it to run for a couple of minutes and then was able to start the unit. Allowed it to run for 10-15 minutes and turned off the key, everything shut off as it should. Turned the key switch back on and the fuel pump started running and the unit started again. Replaced the bad relay. Now to see if I can find a reason for the failure. Relay failures are unusual.
