Since my last post, the snow has melted and I was able to hire a front end loader to push my machine inside the shop. I had hoped by thawing it out for several days that it would have been something frozen up. Not so, same problem. I took off the drive belt cover and the belt looks good, it's turning the Pulley. I have now noticed the only light on my BICS control that's working is the PowerLite. Also my traction lock solenoid works and lights up. I checked my fuses, they're all good. It seems strange that my seat sensor, my lift bar Sensor and my auxiliary hydraulics lights would all go out at the same time. I'm thinking I may have a faulty Bics controller. Is it possible to bypass all of that stuff and jumper wire the solenoid that is locking up the hydraulics to see if the machine will operate at all? If so, which solenoid would it be? Does anybody rent that MEL 1428 sensor tester? Is it possible to test the seat bar switch and the lift bar switch without the sensor tester? I'm inclined to believe the switches are not the problem because they all went out at the same time. Any help would be greatly appreciated, thank you
