I have a 2005 Kubota b7800 tractor that just stopped running. I removed the fuel solenode and cranked the tractor. I checked the solenode by running two wires from a battery and nothing happened. I ordered a new solenode. I got the new solenode and put it on and the tractor will not crank. I checked the new solenode like I did the old one and no click or pin move. Why not? I checked the wires going to the solenode with a test light and there is no fire. Could it be the switch?

Remove and fully charge, or replace, the battery.
