I have a Belarus 250/310 that I have to play with the starter
solenoid every spring. The wiring inside mystifies me. I know
how to wire the solenoid to the tractor, and how it works, but
every spring I have to play around with it, and eventually I get it
to work, but I'm not sure how/why.
The solenoid, which is mounted on the starter has two big
electrical connection bolts. One goes to the tractor battery, the
other is connected to the starter itself. Inside the solenoid one
bolt has no connections and one has a wire that goes into the
solenoid coil. When the solenoid coil is energized, a disk makes
the connection from one bolt to the other, turning the starter
motor over, and also pushing a gear to connect to the flywheel.
The only other connection is the stud which is connected to the
starter switch on the dashboard. This stud has two wires
which go into the solenoid coil. When the starter switch sends power
to this stud, it should energize the solenoid coil connect the
starter motor to the battery power, and connect the starter
motor bendix gear to te flywheel.
There is of course also a ground circuit to the starter and
solenoid...
The problem is that it doesn't always work. Why are there three
connections to the solenoid instead of one ( plus ground)
Thanks, Jim.
