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.

I just replaced my batteries in my E15, since I was down to about 15-20
minutes of mowing time. 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
