AG-237 Growler

AG-237 Growler – Armature & Coil Insulation Tester

The AG-237 Growler is a rugged, workshop-grade testing tool designed to locate shorts, opens, and grounds in electric motor coils and armatures. Built in Australia by Durst, this universal growler provides accurate, non-invasive diagnostics for motor repair professionals, rewinders, and service techs handling armatures ranging from 50mm to 130mm in diameter.

With a 1.5 amp output, the AG-237 is ideal for identifying faults in electric motors, generators, starter motors, and similar coil-based systems—without dismantling windings. Housed in a durable, bench-ready casing, it’s a go-to tool for every electrical maintenance bay.

Frequently Asked Questions

1. What does the AG-237 Growler test for?
   The growler identifies short circuits, open circuits, and ground faults in armature windings or stator coils. It uses magnetic induction to pinpoint internal faults without dismantling the motor—saving time during repairs.
2. What size armatures is this growler designed for?
   The AG-237 is designed to suit armatures with diameters between 50mm and 130mm, covering a wide range of automotive, marine, and industrial motor components.
3. Is the growler safe for sensitive motor components?
   Yes. With a controlled 1.5 amp output, the AG-237 provides sufficient field strength to locate winding issues without damaging insulation or other motor components.
4. How is the growler used in diagnostics?
   Once the motor component is placed on the growler, a feeler (such as a hacksaw blade) is moved over the surface of the winding. Any internal short will cause the feeler to vibrate due to magnetic field distortion, indicating a fault location.
5. Is this a portable or bench-mounted unit?
   The AG-237 is a bench-ready unit, weighing 12kg for stability and ruggedness. It’s suitable for permanent use in electric motor repair shops, fleet workshops, and electrical service bays.
