Re: GX345 Time Delay Module
Well for $20.00 (actual price from John Deere Dealer in Lancaster OH), I picked up a TDM this morning and replaced it and it 100% fixed the problem. NO more cranking and waiting and cranking...no more coughing and dying and waiting to restart. Best $20 I've spent in a long time and worth it.
Also, it's a GOOD idea to thoroughly examine and clean all electrical connectors as well. In working this issue I found the coil wire connections corroded. On the RIGHT coil, when I attempted to remove the wires to clean the spades and connectors, one of the spades on the coil actually broke off at resin level! SO that was a $50 coil to replace. The wire connections on the LEFT coil were also in terrible shape, so just replaced all the connections with new ones, and once I attached them to the coils, I used liquid electrical tape to generously coat the connections to prevent new corrosion.
I found connectors on the ignition board to be cruddy and dirty and they required cleaning with CRC Electrical Contact cleaner. I found the stud, bolt and connections under the starter to be corroded as well and I removed all those and cleaned them when replacing the TDM. Where the TDM grounds to the bolt (one of the two bolts that holds the ignition ignitor) I found another bad ground wire that needed a new connector. I also found a hole about 3/8" in diameter that either had burned or eaten or worn thru the top of the ignition ignitor (near the upper bolt). I was going to replace the ignitor until I found the price was $275 (dealer price). So I figured I'd patch the hole and see if it still worked. It did, so I didn't have to spend the $275 for THAT.
So to sum up, the TDM fixed the issue, but I also found corroded and broken wires which I replaced. I also make it point to keep those battery terminals clean and corrosion free.
