Nick,The seat switch is actually disabled on mine. If I remember correctly, it was like that when I got it, and during the restoration I decided not to fix it, since it was helpful during the trouble-shooting to not have to be on the seat when trying things out. I'll double-check that switch though. If I remember correctly, there are two wires that go to that switch (which get connected when you sit), and they're just shorted together on mine. All the terminals are nice and clean, and the batteries are charged. They're these batteries:

Something that may be related - while I was removing the old Trojans, I accidentally dropped my wrench and shorted between two of the batteries underneath the seat. Nice sparks and such. But - the front two batteries were already disconnected at that point, so there was no closed circuit through the tractor, so I wouldn't think the short would have done any damage to the tractor's electronics. I got a nice burn though. :)

Make sure the battery terminals aren't interfering with your seat switch operation. I had a friend's E15 show very similar symptoms where it seemed like the seat switch was just on the edge of intermittent contact because the new battery threaded posts were just a little too tall. These were Crown batteries in his tractor. I'm assuming that you cleaned the terminals well and that the batteries were charged when you got them.

With the new batteries, I pushed the speed lever forward, and just got a bunch of clicking. I checked the forward/reverse relay, and it looks like it's blown - so I replaced it with another (I have lots of those onhand). Now, when I move the speed switch to the left to put it in reverse, the new relay just makes a constant clicking - as if it's rapidly switching back and forth or something. When I try to get the tractor to move (forward or reverse), I still just get that clicking, and no motion. Any ideas? On a related note - is the Alltrax the only option for upgrading to a PWM controller? Thanks, Mike
