...this topic was originally at lawnsite.com. I brought my post over here to condense some of the Zeon tidbits floating around the net.
The following may be of some help to other Zeon owners. When I first got my Zeon I was plagued by the code 2A62 and sometimes 2A65. This code locks up the machine leaving you sitting wherever it happens (in my case most recently at the post office LOL). I contacted former Zeon owner "Hustler Zeon Owner" (who originally started this thread) and he was able to give me some important insight and clues as to the behavior of his Zeon and how the dealer handled it.
I noticed that it would give the code 2A62 (the right side), but also that I could clear the code (sometimes) by holding the left park switch with my thumb, while jiggling the right handle. So we know that the right and left handle position sensors are on the correct sides (obviously), but the park switches might not be. Here's what's happening on probably all Zeons with the 2A62 problem. In order for the park brake to release at startup, two conditions must be met: the park switches must be closed (handles out), and the value of resistance at the handle position sensors must be below a certain limit. After raising the rear, and bypassing the damned seat switch, I found that both wheels had some very slight forward or reverse motion when the handles were in neutral (but not in park) position. The handle position sensors themselves have no adjustment, so the adjustment is made by changing the position of the handle dampeners (for lack of a better description). They look like shock absorbers on each side, and their purpose is to hold the handles in neutral and provide some resistance in forward and reverse. Adjusting these dampeners (both have a slot at their mounting point) until the wheels don't move, is the ticket. The fact that the park switches are on the wrong side doesn't cause the problem, but confounds anyone (even the dealer) trying to troubleshoot the issue. I have no plans on reversing the park wires, but I will leave the seat switch bypassed:). I consider the problem solved. I drove it all over today, and could not get it to fault out. To correct the problem follow these steps:
1). Raise the rear wheels off the ground
2). Bypass the seat switch (I leave mine bypassed)
3). Remove both handles
4). Remove both side covers
5). Use a tester to check the park switches (check for continuity) just to be sure they work.
6). Turn on the machine
7). If it turns on and says ready, move the levers out of the park position.
7a). If it doesn't say ready, you will have to **** with it until it does.
8). If the wheels start to creep, adjust the "handle dampeners" until the wheels stop moving. The adjustment is made using a wrench from inside the battery compartment, and another to keep the bolt from turning.
9). When both wheels don't move your problem should be fixed.
10). Try shutting it off and back on several times before putting everything back together.
11). When you are confident that the problem is solved, reinstall the covers and handles
I hope this helped you.
***UPDATE*** I won my Zeon on EBay with 44 hrs on it. Ive used the heck out it this summer: mowing, mulching leaves, towing a small cart, etc. It now has 89 hours and hasn't given me that code again. It's been a sweet little machine.
