(ET) Seat Switch



From Lee:

There's another side to the seat safety switch story.

If:
1. You don't have a brake update on your tractor and therefore not much brakes, and
2. You are going down a rather rough trail on a hillside, and
3. You bounce just enough to kill the braking power of the engine, then
4. You're going to have one wild ride down that hill.

Been there, done that!  It wasn't my idea of Big Fun!



the safety switch on the
seat is there for a good reason, do NOT by-pass it. This switch will wear
out, get a new one from Bill Gunn. The safety switch on the tractor seat
saved me when I was moving my 22ft sailboat. I forgot to pull the wheel
chocks and when I started the tractor it went stright up, the switch did 
its
job and the tractor went slowely back down and no damage was done. ET's 
will
climb a brick wall if they get traction.

Also the therminal switches need to be checked (all the motors have one)
they are the last line of defence to save your motors.

 There is a fuse link, on the power disconnect. I have successfully opened
one under load. There was a brilliant, but brief flash, and fireball, but 
as
the wire vaporized, the gap became large enough that it self extinguished.
All in less time than it took to describe it. The existing protection I
would proclaim as being adequate.
