Tracing an Electrical Fault on a Driveway Gate (Video)

What this video shows
Tracing an intermittent fault on an electric gate: supply voltage checked at source and at the operator, terminals inspected for corrosion, and accessories isolated to find a short — rather than replacing parts one at a time.
The fault
- The gate would open two or three times and then become too weak to complete its travel. Leaving it overnight restored a few more cycles. The owner had been told the motor was failing.
How it was diagnosed
- Load-tested the battery. It held voltage at rest and collapsed under load — the classic signature of a battery at end of life.
- Checked charge input. The solar panel had been progressively shaded by a tree that had grown since installation, so the battery had been running in permanent deficit and cycling deeply for a long time.
- The motor and board tested normally throughout.
The fix
- Replaced the battery and relocated the panel to a position with genuine unobstructed sun rather than convenient mounting.
- Verified charge current at the controller and confirmed the battery was recovering to full between cycles.
On solar gates the power system is the first thing to test, not the last. A tired battery produces symptoms indistinguishable from a failing motor and costs a fraction as much to fix. It is also worth checking what has grown near the panel since installation.
