TROUBLESHOOTING ENGINE
NOTICE
■
The following test must be performed with an
accurate voltmeter. The amperage in this circuit is
too low for a test light. This circuit is the ground
side of a relay.
1.
Check seat switch and deck safety switch/jumper.
a.
Raise seat assembly and secure with prop rod.
b.
Turn key switch “ON”, engage seat switch and
move deck to highest cut height position.
c.
Check voltage at the pink and black wires on the
main wire harness where it connects into the seat
switch wire harness. (2 way Packard 56 series con-
nector located underneath seat pan on the right
side next to steering pivot block.)
• If there is voltage at one wire but not the other,
either the switches/jumper are defective or not
fully engaged. The pink and black wires are part
of a series circuit that includes the seat switch
and deck safety switch (on power tilt deck) or
weatherpack jumper.
• If there is voltage on only one wire check each
switch ((seat switch, deck safety switch, (located
on the deck), or weatherpack jumper)) individu-
ally to determine which switch is defective or not
closed. The weatherpack jumper should be con-
nected to the main wire harness, underneath the
seat pan by the left hand steering pivot linkage if
there is not a deck or a standard deck is
attached.
• Check the deck safety switch refer to Figure 10
and troubleshooting deck safety switch. If the
deck switch is open the engine will kill when pull-
ing handles in.
Figure 10
. Power Tilt Deck Safety Switch Layout
• If there is voltage at both pink/black wires men-
tioned in the previous paragraph, check voltage
at yellow/red parking brake wires with the park
brake off.
• If voltage is not present, the wire between the
seat relay and parking brake switch is uncon-
nected or the seat relay is defective and must be
replaced.
• If voltage is present at one wire but not the other,
the parking brake switch is defective and must be
replaced.
