JOHN DEERE 310G WIRE IDENTIFICATION

[missp672000]

I HAVE A JD 310G BACKHOE WITH ENGINE 4045DT058. IM TRYING TO FIND WHERE WIRE E02 GOES . IT STARTS UNDER THE FLOOR PANEL IN ONE OF THE BIG PLUGS. THERE ARE 4 OF THEM. IT GOES THRU WIRE HARNESS AND ENDS UP AROUND STARTER. I DONT KNOW WHERE THAT END GOES. IT IS HOT WHEN THE KEY IS ON. THANKS

All CAPS says you are yelling.

Please post the machine's complete serial number since there are 5 different schematics to compare. Want to give you the correct information.

E02 white wire typically goes to the "S" terminal the starter.

 

[missp672000]

LOL Im not yelling. It is easier to type in all caps. Thanks for replying! The Product Identification Number is T0310GX947394.
The serial no. is 640913

This is the Machine's serial number I was looking for, thanks.

Confirmed. E02 White wire should go to the "S" terminal on the starter solenoid. The other end goes to the K5 Parking Brake Latching relay, which is located in the fuse panel.

 

[missp672000]

Thank you very much! Would this keep it from cranking? Now Im confused. The wire is in the wire harness on the opposite side of the engine from the solenoid. I dont see how it can connect to the solenoid. Can you please explain. Im not very good at mechanical work as you can see.

 

[mg2361]

Would this keep it from cranking?

No. That wire is for the park brake circuit.

Do you know how to read a schematic? Check your messages for the start circuit schematic.

Check your F13 10A fuse and the F12 10A fuse first.

 

[missp672000]

The fuses are good. The wires match the schematic as far as i can tell. There is a gray plug under the floor panel. There are three of them together. The wires in the plug are white-E02,E23,E25 BLUE-T11,T13,W55,W02 RED-P13,B03,P12 PURPLE-M32 and an off white or pale yellow J27. Its hard to read. I can trace all the wires except E02. It ends up close to starter but is broken and I don't know where that end goes. It doesn't split off in any other direction and it is the only E02 wire I have found.

 

[mg2361]

Edited, ignore.

I can trace all the wires except E02. It ends up close to starter but is broken and I don't know where that end goes.

It attaches to the "S" terminal on the starter as I mentioned earlier. That is the terminal that engages the starter. It should come out of the harness right there near the starter (from the rear of the engine).

 

[missp672000]

My starter doesn't have a solenoid. Wire E03 comes from start relay on frame and clips to a screw on the bottom of the starter. The starter engages and spins good. So is E02 maybe an extra wire

So is E02 maybe an extra wire

Does the park brake release?

 

[missp672000]

I dont know. I used the machine everything was working fine, went back a few days later and it would not start. In trying to figure out what is wrong with it I noticed the wire E02 not connected to anything. It was previously connected but I cannot find where it went. It is driving me crazy! The wire is hot when the ignition is turned on

 

[missp672000]

If the parking brake switch is off when trying to start it will not crank. that's why I was wondering if the E02 broken wire is somehow keeping it from starting

 

[mg2361]

Again, as mentioned, the E02 wire has nothing to do with starting, so ignore it.

Does the machine crank and does not start? Or does it not crank? The answer to these questions will change the diagnostic flow path.

 

[missp672000]

it cranks, but will not start. it will start as long as you use starting fluid, but dies when you stop spraying it

 

[mg2361]

When cranking, does the rpm appear in the display or does it show dashes?

Also check for diagnostic codes. Check your messages for the procedure.
