I was using my Walker the other day in some thick grass when the shoot stopped up so i shut the mower down to clean under the deck. When i went to restart the mower it would not start. My ringer will cut on when i turn the key but nothing happens. I've checked my battery at the auto store and it was good, cleaned my termals on the batt. reset my switch. The meter on the mower show 14volts when the ringer sounds but when i turn the key it goes to 0volts. I've tried to check my safety switches but nothing. I think that my other walker did this and it was a wire up under the mower loose, but i cant seem to find it on this one. Please Help!!!!!!
