Circuit Operation

Battery voltage is applied to the park neutral position switch terminal B through CKT 339 (PNK). When the park neutral position switch is in park voltage is applied to terminal A of the stop/BTSI/cruise break switch through CKT 275 (LT GRN). when the stop/BTSI/cruise break switch closes voltage is then applied to terminal A of the shift interlock solenoid through CKT 1135 (DK GRN/WHT). With the nominally grounded CKT 850/50 (BLK) the relay engages allowing the transaxle to be shifted out of park.
