90% certain that several years ago I bench tested several
drive and attachment motors, using two 18v cordless drill
batteries connected in series. Obviously not a lot of capacity
but 2 seconds just to test each motor. Recently, however, I
recreated that setup on an E20 motor with bad results and now
I am doubting what I (think I) did successfully back then.<img

time the motor spun very slow for about a half turn and
stopped. Worse, when I put one battery back into the drill, it
was 100% gone, and then would not recharge- ruined. I then
rethought everything and decided that that battery must have
been the problem so I brought out another E20 motor tagged as
"runs good" and repeated the setup (replacing the dead drill
battery with another). Same basic result, however this time
both drill batteries worked afterward. Should this setup work
or is my recollection faulty?</div>

<div id="yui_3_16_0_ym19_1_1544182759136_3393" dir="ltr">1. I
had attached the leads from the makeshift battery pack to the
two terminal studs labeled A1(red 8) and S2 (black 10) as
shown in fig. 7-8. Concluding either lead on either terminal
would not matter. I did not do anything with CB-1, it remained
unconnected. Field weakening plug was also unconnected.</div>

<div id="yui_3_16_0_ym19_1_1544182759136_3393" dir="ltr">2. I
decided to test in the first place because I had loosened the
terminal nuts and was surprised how loose the terminal bolt
becomes. (I am restoring this tractor and am obsessive about
cleaning/shining all bolts and nuts). Then I was concerned
about what might have happened internally when the bolts moved
around so much. I found an exploded diagram of E20 motor on
George's website and saw that the bolts have a tapped head
with a wire attached, the terminal bolt is held/restrained by
an internal flat washer. So I was comfortable repositioning
the bolt and washer, the square spacer, and the insulating pad
to their original position and then re-tightening the nut.</div>
