Most seat switches that MTD use are NC switches. This
means that when the operator leaves the seat, the switch
closes, allowing a ground signal to pass through it.
th
However, the 50 anniversary edition (GTX2154LE) is
equipped with a special high back seat. This seat comes
equipped with a SPST NO switch. This means that when
the seat is empty, the switch is open, blocking the ground
signal.
NOTE: The harness to seat switch pig tail connector is
attached to the seat bracket. If the connector is
allowed to hang free while the seat is moved, the
connector can be pulled off of the seat switch pig
tail, shorting the circuit. See Figure 7.10.
NOTE: The seat switch for the 50
part the seat and can not be serviced separately.
To overcome this problem, two relays are used to
reverse the function of the switch. The relays also split the
ground signal to the RMC module and the safety circuit.
The circuit functions as follows:
• The RMC and the safety circuits receive a ground
signal through the NC contacts of the seat switch
relays. See Figure 7.11.
• The windings of both relays receive battery power
from the A1 terminal of the key switch.
• When the seat is occupied, the windings of both
relays are grounded.
• The relays energize, breaking the ground path to
the RMC and the safety circuits.
NOTE: Both of the relays are taped to the harness by the
hour meter. See Figure 7.12.
