Lab-Volt 91020-20 magnetism board Repair Service

Professional diagnostic and board-level repair service for this Lab-Volt 91020-20 magnetism board.

Lab‑Volt 91020‑20 is a magnetism/electromagnetism training board that provides hands‑on experiments with magnetic poles, lines of force, solenoids, latch circuits and buzzers. Common failure points for this type of educational board include burned or tripped protection diodes on the power rails, damaged MOSFETs controlling the electromagnet coil, and loose solder joints on the buzzer or latch output pins. Initial checks should verify that the 5 V/12 V supply rails are within spec, inspect all visible traces for burn marks or broken connections, and confirm that the coil driver outputs produce the expected voltage/current when a test load is applied.
