WebJan 20, 2024 · Generally you can tell because a 1N4148 is typically marked '1N4148' on the body, while a Zener diode has a different marking. You may need a magnifying glass to make sure though, because other diodes can have quite similar markings. If the markings are partially rubbed off it might be difficult to tell the difference. WebSep 5, 2005 · 2,676. Beavercreek, Ohio, USA. The best and easiest way to test the diode block while the alternator is still on the engine is to do an AC ripple test with a digital multimeter. Just start up the car, turn on the headlights to remove surface charge off the battery. This will force the alternator to switch on.
