in need of someone's help

[llhrpm]

Hello, i am new to this forum and first off ill say you guys have a very nice site here... but anyways to my problem i have a dynamark riding tractor and i have a starting problem. it will not start by the key and i have checked all the wires and everything batteries brand new and so is solonoid. i was thinking it may be the wires going to the key... if anyone has any ideas your help would be greatly appreciated :thanku:

Is there a fuse between the ignition switch and solonoid?Or it could need a new switch.
