   I have been fighting this mower when i get time for the last month. It was running fine at the beginning of the season parked it 2 days later it wouldn't start. It will not crank the starter just makes a click from the drive kicking out and i lose all power. Some times when holding the key in the cranking position the computer will start to flicker on and off. I have 2 more of these machines so i have swapped out all relays the batter had the starter rebuilt, swapped key switches, tried jumping the starter straight to the battery and no change but all the parts when put on another mower it starts right up. I have cleaned all grounds and the positive terminals. I have run out of ideas and the JD tech just wants to make a service call or have it brought in which may boss wont do. So if anyone else has any ideas or has experienced this i am looking for any other things to try.

   Yes I have tried 2 other batteries from the other 2 3235's we have and the battery from this machine starts when in the other machines.

   I had a similar problem with an old jacobsen.Are all your wiring cables good you might have a bad connection somewhere.

   Use a jumper cable from your Battery negative to ground and attempt starting. I have experienced bad spots in ground cables that read correct ohms to ground but the bad spot resists current.

   The easiest way to find your problem there, is a starter voltage drop test. It will be fast and accurate. All you need is a good volt meter and a little info. You can find step by step instructions on how do it, right on youtube.com I send you there because it will be easier to understand than me trying to explain it here, and you will learn the correct way of testing for these problems. You will be able to check both Positive and Negative sides of the starter circuit. I often refer back to the videos for refreshers when I think I'm missing something or it's been a while. This procedure takes all the guess work out finding your problem. Just type in Voltage drop test, or Starter Voltage drop test. There will be many videos on how to guide you through the test. Once you get the hang of it you will never use anything else for electrical issues.

   Motorage Magazine has done some of these videos on this topic and I found them really easy to comprehend and learn this procedure that Skip is fond of. I have to say it works quite well. I used it to find a key off draw on a Suburban that I couldn't pinpoint any other way.

   Does your computer stay on long enough to get any codes? I had a similar problem a few weeks ago and checked the seat switch and then found out it was the mow switch under the floor board. Replaced switch and adjusted linkage and has run just fine ever since.

   Ok Finally had time to get back to this mower. Tried a voltage drop test had 12.6V at battery and then on the starter I couldn't get a reading because it was jumping between open line and the readings. So i swapped out the starter and it works just fine on a different mower. What I have now is when i turn the key to the run position everything is fine lights come on fuel pump is running and the computer doesn't show any codes and all the lights that should be on are. When i turn the key to the crank position that is when the computer flashes as do the lights by the key. It also sounds like the relays are having a hard time working.
