    John Deere 310D electrical problems, please help!

    Me too, Deon and your right, it takes patience to track down electrical problems. I told the neighbor that I thought this happened because he left the hoe parked out in the field for a couple weeks, instead of in his barn where the mice have other things to eat. It was my pleasure to post up my...

    John Deere 310D electrical problems, please help!

    Ok, here are the pics I promised earlier. The final place I found chewed was in the K1 starter relay harness between the engine block and the hydraulic tank. It was a real nightmare to try to get to without pulling the entire engine harness out of the machine. I didn't have continuity between...

    John Deere 310D electrical problems, please help!

    Well, after about 5 or 6 hours of studying the wiring schematic for the hoe, I figured out a good test sequence and followed through with it. I figured out which wire in the main harness plug between the cab harness and engine harness and tested for signal to crank there. Had signal coming from...

    John Deere 310D electrical problems, please help!

    Yes, the ignition switch itself is brand new. We put it in a couple months ago when we were first trying to figure out the problem. I do understand your point though. Signal to crank does leave the console in the cab when the key is turned to crank and checked with the test light but it don't...

    John Deere 310D electrical problems, please help!

    Sorry. I didn't know we aren't allowed to post pics. I guess next weekend I will get back on the job. My next plan of attack will be to double check the neutral safety switch and then pull the hood off to examine the rest of the main engine harness.

    John Deere 310D electrical problems, please help!

    Well gentlemen, I sure apologize for the amount of time its taken for me to get to work on this job! My neighbor, (the man that owns the backhoe I was working on) took the hoe to a job and didn't bring it back home till last weekend. As I said before, I have found a couple places where mice had...

    John Deere 310D electrical problems, please help!

    Well, as luck would have it, a couple things came up and we wasn't able to work on the hoe yesterday like I thought. We are planning on spending next Saturday on it and hope we will be able to get her finished. I will update our findings then. Hope everyone has a good week.

    John Deere 310D electrical problems, please help!

    Deon, I didn't get to work on the hoe last weekend like I thought I would. The wife's honey-do list prevailed...LOL!! I did get to spend a couple hours with it today though. I fired the hoe up and jacked it up as I high as I could using the stabilzers and front bucket. I took a drop light...

    John Deere 310D electrical problems, please help!

    Yes, I am sure its working. It lights a test light and doesn't change anything when swapped out with a known good relay.

    John Deere 310D electrical problems, please help!

    According to the schematic, power to crank from the F-N-R switch relay, (or K-6 "Neutral Relay") should run directly to the starter relay K1 out under the hood. I have checked this K1 relay and it is not getting signal to crank the engine. The parking brake is not part of the crank circuit so I...

    John Deere 310D electrical problems, please help!

    Johnny, sorry it took me so long to reply. I must have missed the email telling me someone had posted. i didn't get a chance to work on the hoe last weekend but I am going to make some time this week as I have a few extra days off work for the holiday. I read the owners manual and found that...

    John Deere 310D electrical problems, please help!

    Deon, Thank you for watching over this thread. I don't think that is the problem in this case. This hoe has mild surface rust on the hood but other than that she is pretty clean. I can see where the harness comes through the frame under the console and it looks fine there too. I could do the...
