With a gnd on JP1(3):
a) pin 1 of the 40106 s/b less than .2volts reading 0V
b) pin 2 s/b greater than 3.5V, reading 4.92V
c) pin 3 s/b the same reading as pin 2 reading 4.92V
d) and pin 4 s/b < 1v. reading 0V
With JP1(3) open:
e) pin 1 of the 40106 s/b greater than 4.5V reading 4.92V
f) pin 2 s/b<1V reading 0V
g) pin 3 should read the same as pin 2 reading 0V
h) pin 3 s/b greater than 3.5V. reading 4.97V
Moreover, on the motor connector I read 2.37+V when it is not moving.
Shouldn't it be 0V ?
