Re: (ET) Alltrax install!

[Rob Brockway <getractor yahoo com>]

I hear what you are saying, but I think a built in temperature switch is a really good thing.  It shuts things down when the core temp of the motor gets to high.  I think it is simple, direct and complements the controllers protection.

A simple question, with some great safety concerns.

The only time in a pre-Alltrax machine, that my overheat relay was triggered
was pulling or pushing up a steep hill. In that situation, I do not want to
"coast" anywhere!!!

The Alltrax controller protects the motor by not getting it overheated to
begin with!
It measure current and voltage and "knows" what is going on by those
measurements, not some crude poorly working temperature relay.
