Hi guys, i have a ford 445c loader tractor that won't move. I checked the easiest thing first and checked all fuses and they are good. I ohmed out the clutch switch on the left floor board and it is also working as should. I noticed that the backup alarm doesn't come on any more when switching to reverse which makes me wounder if the electric control circuit has power going to it. Does anyone have any suggestions or a direction to send me.
