(ET) tractor no worky

[Michael S Briggs <msbriggs unh edu>]

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
