Re: (ET) Diagnosing delay error on E15 board

Ok, I will have to agree after using this thing for a few weeks that the E15 is cool, but very sub-standard. I really am finding myself kind of liking the throttle, maybe it's because I don't need to keep my foot on the pedal (although the E20 has cruise control that makes that good). It's not intuitive, but I do kind of see the appeal.

As long as the brakes work.

But the E15's control system is terrible compared to the E12 and E20. Reversing the field was probably the stupidest idea they could have come up with; I don't know who thought that one up but they should have been forced to carry the tillers to the dock. The E20's contactor reversing of the armature equals no problems, and if they do start to go you can simply flip and reverse them and get another 40 years of life.

So yeah, I can see why a poor befuddled E15 owner would say "That's enough" after burning up yet another relay. The fact that simply moving the throttle switches the relay is silly enough. If you're at speed 0 the field should be *off*, no exceptions.

Maybe that's one thing that killed the Elec-trak; once they started selling the cheap controllers they more than lost on the service calls and returned units. The E20 would have been a tank by comparison.

Ah well.

This is not to say that the Alltrax is the only suitable controller or
necessarily even the best.  There are others.  Almost any, with the 
possible
exception of the really cheap Chinese sweatshop junk, would be more 
reliable
than GE's 3-decade-old parts - and more pleasant to use, too.
