Re: (ET) Trouble, first two forward speeds



My thanks to all who replied about my trouble three weeks ago with my two first forward speeds. (See description below.) I didn't do any diagnosing because it.... "fixed itself." Naturally, I know that since electromechanical systems heal themselves all the time, I won't have to keep your good suggestions handy. ;-)
 
But seriously, it ran like a champ to blast through the last Boston "Chowdah" we got dumped with... wet stuff.
 
Two notes on keeping the chute from clogging... (I forgot who asked, but two did)
1- I rub a cake of paraffin wax in the chute from time to time, just to keep the surface rust from being a sticking site for cold but wet snow
2- having a few seconds of serious current available to push out a nearly clogged mass is handy; that's where the second set of six batts comes in. They're heavy and they can be ol' beaters, but they help. See also http://www.maxmatic.com/electrak.htm
 
Best to all

Hey team,

my hard-workin' E20 came a-cropper today. Symptoms...
- reverse is fine, behaves as normal
- forward though, does these:
- on the first "click" (as you push the lever from off) the motor doesn't turn, but lots of current is drawn (in the yellow range on the "power use" meter)
- on the second click, same behavior, roughly the same current
- on the third click, there's a short delay (<1 sec) and the motor takes off (and current draw goes into the red)

So I surmise that the control for either the field or armature winding is bad. Sane?

Thus...
- I wonder if you agree with my thinking so far
- and what I should do next!
