I have been a quiet veiwer that has learned much from this site for repairs. I have got to the point where I have to ask for help. We had a extreme cold spell this winter. I had to jump start to get it going to plow my driveway. I noticed a auxillary line to plow had cracked down near the plow. Hydro fluid appeared to be close to full far as I could see. I let it run for 1 1/2 hrs to thaw well. It shut itself off and displayed error02. It will start in service position Sit on seat (1) sensor and lights come on Seat belt switch works. I made a bypass toggle switch to speed up troubleshooting process. I replaced pressure switch AT321216 I replaced ignition switch Can I jump around the hydro pressure switch? Or is .that not a open/closed type? Does that have to send a resistance range to the board? And how would. I test that ? Thanks for any help ! I have a ton of work to do on property, it is like missing a limb! I described the scenario of the breakdown and my repair attempt s best I could. Thank Thanks again!
