4310 Ehydro no move...AGAIN...replaced controller...AGAIN

[mfreund]

When the light on the fender flashes, it is actually flashing a trouble code. Count the short and long flashes to determine the code. That will point you in the right direction where the problem is. We have sold literally hundreds of these since they have been made, and we have replaced only 2 controllers in all that time. Vast majority of the time, a forward or reverse sensor needs to be calibrated when they won't move. Most other times, a bad connection, loose or broken wire or a bad sensor is at fault.

x2!!!

I agree with Steve, Bad ground in there. I would also use a braided ground strap if none is being used. Hard to chase a gremlin in the machine. Good Hunting!!

Sounds to me as if letting the battery go down completely might have something to do with it. I think the dealer is "throwing" parts at it. Can't exactly blame them. If it is the connectors and they hook up a new one and it works, its easy to think the old one is bad.

Clean the connectors. Add a little dielectric grease. Clean all grounds, make sure they are tight. Clean the battery cables. I agree a low battery will cause electrical problems that go away when a fully charged battery is used.

I own a 2010 JD 3520 with Ehydro, and I am very disappointed only 500hrs on the machine . I have the same issues, the tractor will go into gear when ever it feels like it. One day I was clearing some dirt over a bank at my farm. As I approached the edge of the bank , I dumped the load, selected reverse, accelerated and just about drove forward off the bank even thou I verified that the tractor was selected to reverse . Any idea's

Thanks for all the help folks...I was also thinking either a loose wire or bad connection. A computer
usually either works, or doesn't work. This thing would work part of time and not at others. I pulled
it apart to get at the controller prior to having the dealer pick it up...I smeared dielectric grease on
the connectors, but I didn't get a look at the ground strap...I'll check it out.

I highly suspect that the dealer is just throwing parts at it, instead of listening to the symptoms and
troubleshooting. This being the THIRD controller, tells me either deere has a big QC problem on their
controllers or the dealer isn't finding the REAL problem. I have called the dealers maintenance
manager and asked to have a Deere regional rep get in touch with me regarding this problem, since
either way it's a black eye to Deere.

The tractor still had the problem after I replaced the battery...with a John Deere battery from the
same dealer.

Anyone had any luck getting Deere to help with the cost of replacing these kind of parts ? I know
it's out of warranty, but this this tractor is kept inside a climate controlled space, and only mows
grass, and a little light loader work.

I don't believe I've read anywhere else about a controller being replaced. Only loose wires underneath by the pedals. Need to make sure my battery never goes dead.

Most people put the Optima gel batterys in the 4310's. The stock batterys leak a bit of acid when jarred by a stiff ride and it can rust out your front metal components in the battery area.

I'm on my 2nd Optima and my tractor is a 2002 model. The 1st battery got changed when I noticed the above condition when it was about 2-3 years old.

Well, folks you're not going to believe this but the controller on THIS 4310 just went out again....almost EXACTLY a year from the last one. No trouble codes flash, in fact,
the trouble light never illuminates when you turn the key to the on position. Checked the fuses...all fine, checked the connections, no problems. I am at a loss...this thing
is just a lemon or it hates me !!

Out of all the posts you got , What did you do besides the controller?

As rare as controller replacements have been, I have to think your problem is elsewhere. It's like lightning striking the same person more than once. I know, there are very rare instances of this, but I still think your problem is elsewhere. Pinched wire, heat builds resistance, something. I would be replacing every wire that has any type of kink or anomaly in the drive pedal servos all the way to the controller.
