Check FilamentNIS0005Z
1. When measuring voltage, wrap tin foil around the top of the neg-
ative probe. Then press the foil against the wire with your finger.
2. Attach probe circuit tester (in Volt range) to middle portion of
each filament.
3. If a filament is burned out, circuit tester registers 0 or battery
voltage.
4. To locate burned out point, move probe to left and right along fil-
ament. Test needle will swing abruptly when probe passes the
point.
