To the left of the fuel tank there should be a connector that you plug the two wires that go to chopper into. This makes a loop that bypasses the alarm.
Standing BEHIND the machine, on the left side of the rear hood, where the straw walkers are, there is a 2 wire connector. Both wires NEED TO BE GROUNDED TO KIll THE AlARM. If you look by the fuel tank....good luck!!! You will never solve the problem there.
We had this happen on a 7720 one time and it was the master plug under the seat that wasnt making a good contact we cleaned the big conector and were off good luck please post your results
