247B aux circuit quitting

[John Exnowski]

I have a 247B that will all of a sudden quit while I'm using it but once things start to get warm it will kick out. If i leave it down for a bit it will work again. I'm leaning towards the relay for the circuit but need a diagram of the electrical and the hydraulic circuits. any ideas?

Check the 8 volt supply from the ecm to the roller switch if it is ok check the out put of the switch in neutral its should be 4 volts one way two volts one way 6 volts if this isn't right its the switch if the switch is not getting the 8 volt supply its a ecm problem. But first make sure the ecm is getting machine power aka 12 volts I cant remember wire numbers off top my head ill look this evening

If you want electrical and/or hydraulic schematics please supply a Serial Number. Too many possibilities just to take a shot in the dark.
