I have 2011 troybilt pony 17.5hp briggs&Stratton engine 42" deck, I replaced new battery and new starter, turn key and not even a click, when I had bad battery and bad starter atleast i would get a click, there is a fuse under battery 20amp I checked it and it's good, I get power to starter. if I'm getting power to starter shouldn't the starter atleast engage and try to start mower? it would seem problem is between key and battery, could it be selinoid? I don't even know where to look for it. Wife is on me bad cause i undertook this repair. any help would be greatfull
