Working on a 580B Case backhoe for a friend. The engine temp gauge isn't accurate. With the temp gauge wire removed from the sender, the gauge reads mid range. Does Case use a similar gauge head to others? Also the engine oil pressure light does not come on. Found a wire on right side of engine above starter. Grounded the wire, and the warning light came on. Could not find an oil pressure sender on engine. Could some of the Case people on here help me out as to where the sender should be? Thank you for your help. Now will get working on my 2-105 White so I can use it planting beans when it dries up again.
