Help On John Deere Gt-235?
Posted June 26, 2012 - 06:41 AM
My neighbor has a John Deere GT-235 that is having some issues. He thought since I am a John Deere tractor owner (1979 216) that I could fix his. Wow, a LOT has changed over the years. Here is what the issues are:
Engine runs fine, no issues
Battery is fully charged
Electric PTO switch on dash will NOT engage blades on the 48C mulcher deck
Hour meter is NOT working
I have checked all of the wiring for continuity and everything checks fine with my meter. I have removed the PTO switch and checked continuity on the switch and I have 3 sets of contacts that read continuity either from the Normally Closed contact to Common, or Normally Open to Common. There are 2 additional contacts on the switch with a green and a blue wire connected to them. I read nothing on the meter at these points. I suspect an issue on the circuit board mounted behind the dashboard. I notice there are 3 relays on the board and presume some issues there. There is a red and a green LED light on the circuit board. The green light IS illuminated, so I presume power is at the board, but I don't have a schematic or wiring diagram for the tractor, so any information from anyone here would be most useful. Thanks!!!
