Onan 2500 Start Switch

My Onan in my 1150 has decided to get a gremlin. It has power to the unit itself but neither of the start switches are working. Does anyone know if there are any fuses for the generator itself besides the 5 amp that is on the generator it is good. Any other suggestions would be greatly appreciated.

    There is only one fuse location. Make you are testing the installed fuse and not the spare fuse in fuse cover.
    I would even replace the fuse!
    One drawing shows there is two fuses!

    Thanks there is one 5 amp to the right of the start button are you saying that is a spare? I cant figure out how to get the metal cover off of the start switch to even look. Thanks for the help,

    Well this one has got me baffled. I guess it is time to take it to the shop I have looked over everything that I can think of and I can't get either of the start switches to do anything. If anyone has any last minute help would greatly appreciate it.
