Ash Tray & Cigar Lighter Wiring – Accessory Power Circuits

1932-1972 Passenger Car, 1939-1970 Merc, 1932-1979 PU

Within the Electrical system, the ash tray and cigar lighter circuits operate as controlled accessory power feeds tied into ignition or protected breaker sources. These components are simple in function but depend on correct routing, proper feed protection, and stable grounding to operate safely.

This category applies to 1932-1972 Passenger Car, 1939-1970 Merc, 1932-1979 PU exactly as stated. The Cigar Lighter To Circuit Breaker Wire supplies protected battery power to the lighter element. The Cigar Lighter To Ignition Switch Wire provides switched feed where applicable. Illumination circuits are handled separately through the Cigar Lighter Light Wire and Ash Tray Light Socket Wire, which integrate into the dash lighting network. These wires must maintain clean terminal connections and proper insulation to prevent short circuits behind the instrument panel.

Most failures in this subsystem are caused by brittle insulation, loose terminals, or improper routing under the dash rather than failure of the lighter element itself.

Technical & Fitment Notes

The cigar lighter circuit draws higher current than most dash illumination circuits. Proper connection at the circuit breaker feed is critical to prevent overheating. Loose spade terminals increase resistance and generate heat at the connection point. The ignition-fed lead must be routed clear of sharp edges and moving linkage to prevent abrasion.

Ash tray and lighter light circuits tie into the dash lighting feed. Poor ground contact or degraded light socket wiring results in intermittent illumination. Firewall and dash routing must remain secured to prevent conductor contact with grounded metal surfaces.

Fitment will vary by model year

Inspect feed wires, terminal engagement, and dash routing before replacing the lighter assembly.
