I have a JD LT155. My issues started while mowing, engine died. Was able to restart although dies when parking brake is not applied. I ended up reversing sensor on pb pedal and it works. Other problems have included headlights not working, wire connector on left side of engine melted together, cut connector out and solder connected wires bypassing connector, seems ok. Starting is difficult in winter, takes priming carb with fuel, now summertime will start w/out prime although will only start on low throttle after choking for 10 seconds? i know this is alot but assume it is all connected. Voltage at battery terminals is 12-12.5 volts when running or not also. thanks for any help you can provide...
