17.30. The starter solenoid is mounted at the left rear
corner of the frame. The mounting bracket is vis-
ible beneath the left fender, and the solenoid
itself is accessibly by removing the battery.
See Figure 17.30.

• When the proper safety conditions are met,
(brake applied, PTO OFF) the orange wire with
white trace energizes the windings that magne-
tize an iron core, pulling the contacts closed
between the two heavy posts, connecting bat-
tery power to the starter motor.
17.31. The lighting circuit is hot whenever the engine
is running. It does not draw from the battery, but
runs directly off its own circuit on the alternator.
See Figure 17.31.

Ammeter
Figure 17.32
The solid red wire feeds the fuse with power
picked-up from the battery cable connection to
the "hot" post of the starter solenoid.
The red wire with white trace carries fused
power to the ammeter, and from there to the B
terminal on the key switch.
The ammeter leads both have female spade
connectors at the ammeter, but are male /
female where they connect to the rest of the har-
ness to maintain correct polarity. The female
spade connector that comes off the fuse holder
could be plugged directly to the inboard terminal
on the ammeter, maintaining correct polarity.
Incorrect polarity will have no ill effects other
than a backward reading on the ammeter.
A failed fuse, internally failed ammeter, or dis-
connected ammeter will disable most of the trac-
tor's electrical system.
Remember that a failed fuse has done it's job of
protecting the rest of the circuit from an over-
load. If a fuse blows, figure-out why and correct
the core problem before returning the tractor to
service.
