hi i was wondering if anybody knew how to test a headlight or know of a way you can tell if its still good. im not sure if the wiring is messed up or what. its an fa50
how to test headlight?
Re: how to test headlight?
Ohmmeter across the leads. infinite resistance = bad bulb.

sorry i could you explain that a little better in more simple terms, thnaks
Re: how to test headlight?
allrignt, first you need a multimeter, ($8-$12). This tool is great for testing simple electronics. It has an "ohm" setting that measures resistance. What happens is the multimeter in the ohm setting will tell you how much resistance to electrical flow exists between the 2 test leads. with out the leads hooked up to anything they give a reading of infinity (often displayed as "l" or "OL"), if you touch the leads together you get a resistance of "0" as there is a clear circuit between the leads. So you take the leads and touch them to the terminals on your light bulb, it should give you a resistance reading. The other method would be to set it to DCV for measuring Voltage, and check across the plug that the light hooks into and see if there is voltage present.

^^^ Good explanation, I'd only add one thing:
In order to test for voltage to the socket, the engine must be running.
