FILAMENT CHECK





^ When measuring voltage, wrap tin foil around the top of the negative probe. Press the foil against the wire with your finger. This action will prevent damage to the element.





1. Attach probe circuit tester (in volt range) to middle portion of each filament.





2. If a filament is burned out, circuit tester registers 0 or 12 Volts.





3. To locate burned out point, move probe to left and right along filament. Tester needle will swing abruptly when probe passes the point.
