753F no power to the brake solenoid or hydraulic solenoid . I replaced the controler and push to operate switch . Are there any relays besides the 4 on the engine ? replaced the brake solenoid to. fuses are all good . I'm about out of ideas .
I hate electrical problems. Just make sure when you replace it you don't leave a little plastic shipping piece on it. I think it's to keep the magnet separated. Not sure if your model will have one or not.I think I found it . The lap bar keyed bushing was stripped and turned a 1/4 turn so the magnet wasn't reaching the sensor . This thing has kicked my butt . I sure like working on 610s better .
