Product Overview: The Wanco Arrow Board Controller 7 Pattern LED (part number 203782) is a solar-powered control unit designed to operate LED arrow boards used in traffic management and road construction applications. It features a 7-pattern display selection via rotary switch, automatic brightness adjustment based on ambient light levels using a photoresistor, and battery charge management from solar panel input. The controller operates on 12V DC battery power with low-voltage shutdown protection, monitors battery charging status, and includes dimming functionality. It uses an 18-pin connector interface to drive LED arrow board displays and incorporates voltage regulation circuitry with op-amps, MOSFETs, and switching components to control LED patterns and manage power distribution.

Common Failures
Arrow board controllers may experience issues such as low voltage shutdowns, non-functioning lights, and intermittent operation. Corrosion can lead to damaged traces, degraded components, and defective solder joints. Physical damage from environmental exposure and component wear, such as MOSFETs and capacitors, are also observed.
Repair Approach
Repairs may involve replacing defective components, cleaning and repairing corroded traces, and reapplying conformal coating to protect against future corrosion. The repair process may also include resoldering connections and reassembling mechanical parts if disassembled or damaged during prior repair attempts. Preventative maintenance may include replacing aging components like capacitors.
Testing & Quality
Units are tested post-repair, including diagnostic, load, and burn-in tests to verify function. Components and systems are evaluated to confirm they manage voltage demands, regulate charge, and execute light patterns. Corrosion-prone areas are also checked to verify integrity and functionality.
