Hopefully someone can point out the obvious thing I am missing here. My battery was stored in the warm garage and charged all winter. I put it in a few weeks ago and fired up the mower. I mowed around a bit then parked it. I went out last week to actually mow and it would not turn over at all. I hooked up the charger but it said full charge... I have tested what I can think of. The solenoid activates when I touch it with the charger leads but no starter spinning. I can use the charger directly to the starter and it spins but doesn't engage with the motor (maybe not enough amps from the charger I assume) I have checked the 3 safety switches mechanically, they are all depressed. I have not tested them with multimeter but I assume they are either touching or not, they don't appear to be broken. Is this a bad assumption? I replaced the ignition switch last summer and it looks nice and clean and appears to turn appropriately. I have 12 volts between the green and red wires on the back of the key. I tried to jump from the red to the orange wire to the solenoid but nothing. Maybe I need to tie in some of the other circuits on the back of the key before it will work that way? The only sound I can hear when I connect the battery or turn the key is a muffled click, or tick from the front of the engine somewhere behind the air filter, I have not torn apart the engine to see what it is in there making that noise but it is clearly not the solenoid (in back of tractor) not the starter (other side and back of the engine). I am feeling like it is the key switch but don't know how to bypass the key and try to start to rule that out. Any ideas would be greatly appreciated. Thank you anyone!
