n If engine starts and runs but dies when either
steering lever is engaged, check the follow-
ing. Make sure the parking brake is released.
The steering levers cannot be engaged with
the parking brake on. With the key switch
“ON” and the seat switch engaged, check for
ground at the two yellow wires on the seat
switch. If there is ground at one wire but not
the other, either the seat switch is defective or
it is not being activated properly.

n If there is ground at both yellow wires on the
seat switch, check for ground at the yellow
wire on the parking brake switch. If there is
no ground, the wire between the seat switch
and the parking brake switch is broken. If
there is ground at the yellow wire, check for
ground at the white wire. If there is no ground
at the white wire, the parking brake switch is
defective and must be replaced.
NOTE: These tests must be performed with an
accurate voltmeter. Do not use a test light; the
amperage in this circuit is too low to properly
light a test light. This circuit is the ground side
of relay A.
