Turn Lamps

With the ignition switch in the RUN position, battery positive voltage (B+) is applied from the TURN Fuse via CKT 141 (BRN), through the turn signal flasher to the normally closed switch in the turn/hazard switch via CKT 16 (PPL).

With the turn switch in the left turn position, battery positive voltage (B+) is applied through the turn switch and through two paths to the lamps. One path is to the left front turn lamps via CKT 14 (LT BLU) and the left turn indicator input of the instrument cluster. The second path is applied to the left tail/turn lamps via CKT 18 (YEL) (USA) or CKT 1334 (YEL/BLK) (EXPORT). The lamps go on immediately. They begin to flash when the current heats up the timing element in the flasher and opens the switch. The turn signal flasher switch closes when the timing element cools. The flasher repeatedly opens and closes the circuit causing the turn lamps to flash. A similar procedure is followed when the turn switch is in the Right Turn position. One path is to the right front turn lamps via CKT 15 (DK BLU) and the right turn indicator input of the instrument cluster. The second path is applied to the right tail/turn lamps via CKT 19 (DK GRN) (USA and Eldorado EXPORT) or CKT 1335 (YEL/BLK) (DeVille EXPORT).
