I've used this mower 10 times to cut about 1.5 acres - it was doing fine until last week.  Turned the key and nothing happened except voltage metet went to the negative.  It had a 150 amp battery.  I went to Lowes and got a 230 amp battery.  Turned key and nothing.  Voltage meter went to the negative just a little.  I'm totally unhappy now since the thing is new 40 hours and it won't work.  Could it be a fuse, a ignition switch module???  I really don't won't to spend too much money since I just spent $1400.  Anyone have the same issue or could you give soem insight.
