Rear Door Cigar Lighters

Battery positive voltage (B+) is applied at all times through the rear fuse block C/LTRR fuse (RH Rear Door Cigar Lighter) and the C/LTRL fuse (LH Rear Door Cigar Lighter) )to the cigar lighters on CKT 240 (LH) and 1740 (RH). When the cigar lighter is pressed in, the cigar lighter heating element is provided a ground path through CKT 550 (LH) and CKT 650 (RH) and heats up. When the heating element reaches a predetermined value, the cigar lighter will pop out, thus interrupting the circuit.
