RE: (ET) one speed, no power E20
Further investigation tonight. By paying a little more attention, it seems
that I do have a difference between speed 4 and 5, although it is very hard
to tell.
Also, if I am driving, and manually switch the throttle on an incline, I am
able to go a little better in 4 than in 5.

Speed seems to come on right away. If I manually hit the switches in the
throttle, motor turns immediately. Also, in neutral, you can hear a slight
difference between speed 4 and 5. Ammeter goes down a little, but does not
change at all on inclines, before the tractor gives up.

THANKS FOR YOUR QUICK RESPONSE. I YELL THANK YOU!!!

I hear a click on speed 1. FR switches in. no clicks for 2-8, except the
throttle switches clicking....
I checked the large Solenoids, by putting 12v across them. They all
CLICKED

The third relay does not activate in reverse. Fourth relay simply never
does anything. I replaced 4th switch, still never switching. Never gets
much voltage across it while driving, according to my Meter.
>> I have checked all the wiring running to the motor.
>Check for voltage on the field. Make sure there is a nice 36 volts going
down there. It should be 36 volts or so in speeds 1-4, dropping down as
you hit 5-8.
OK, I checked the field voltage by disconnecting the 4prong plug from the
motor. Field, which I read on the schematic to be wires 36 and 62, reads
24.8 sitting still then:
Speed 1 26
Speed 2-4 25.7
Speed 4-8 25.8
I am not sure I did this right. But the other two wires made no sense;
Speed 1 3.8
Speed 2 .1
Speed 3 .1
Speed 4 19.0
Speeds 5-8 20.8
Again, these readings do not make sense to me, so I may not have measured
it
correctly. But I did read wires 36 and 62 as the field.
BTW, the tractor goes in a reasonably fast speed from the start, on a flat
section. On an incline it dies. If I come off the throttle,(to what seems
like speed 4) it does better. If I manually depress the fourth relay
(FW),
it either does a little better, or stops, depending on what little speed I
may be getting going up the incline, before it completely stops.
THANK YOU ALL FOR YOUR HELP. Thanks, Chris for quick response!

Don't bother with an Alltrax. It's an E20 :-)
