Finally got to run some beans today and try to get all the small bugs outta the machines. First I had a stuck micro switch on the 30' 973 that kept forcing the header down. Now I have the unload auger stuck out... apparently she needs some grease. The light and buzzer for the stone door will go off now and then even though it is closed. Worst of all the warning system went out, came back on for a while then went out again for good. I have not rotor speed, fan speed, or any other lights there. The green normal light is off but the unload auger light is on. Ground speed works and I think engine speed. All the lights work when you press the test button. Oh, forgot about the alternator that keeps dropping out too, will go below 10 volts for a while then back to normal. Would appreciate any and all help on the warning system!
