Today was mowing, had to get off the mower and pulled the park brake, made sure controls were touching safty switch and when I got off the mower died. Fired right back up and kept going, get to next house and mower won't start. take a wire and jump the seat switch, test it and starts right up, run to dealer, buy seat switch install and starts up again. Think all is good now. Leave dealer get to house to cut, starts up and had to get off and mower died again and would not start up. Knowing there are 4 safty swithes I decieded to jump all four at same time and that way I could isolate problem to which one or more was still bad. Well with all 4 jumped....still won't start, not sure where to look now, checked wiring harness and everything looks to be connected. Any ideas?
