Issue: Client reports no 5VDC. Attempted to replace voltage regulator (U191), not completely installed.
Fix: Removed U191, cleaned pins, and removed damaged pads. Re-installed U191 with jumpers where pads were removed, TP4 = 5.1VDC. Board passed general test (controlled lamps, solenoids, flashers, and GI).
