I have a 2014 45d-9a, 5000 hrs, and did a transmission fluid change this weekend. After I was done I noticed the battery light had come on and never has before. When I drove the machine the speedometer wasn't working either and it always has. Could this be a coincidence or somehow be connnected? I can't find any lose wires and I removed and cleaned all the battery terminals with the same outcome. Any suggestions?
