I appreciate your help, but i couldnt find a shaft sensor anywhere near the straw spreaders. I'm thinking its something electrical because when i turn the light on and then back off the alarm and the light go back off!! But i still cant find the sensor for the spreaders (choppers) OH and ive got another problem........i have the monitor set perfectly (to my specs. anyway) and i'll be driving along and it will read in the green where it is supposed to and all the sudden it will peg-out, and then drop all the way back down no matter what speed you go, ive tried running everywhere between 1 and 8 mph and i cant get the needle to even move. like i said MORE PROBlEMS
