I'm curious what you all do to bench test electrical items? I'm just not very knowledgeable about electrical things. I have some gauges, fog lights and other items I'd like to be able to bench test but don't know the best way to power them. Our cars of course run on 12v systems. Is there some sort of device to use that allows one to adjust voltage?
I know this sounds like a dumb question but I'm sure there must be a safe way to test electrical devices for our cars. Anyone? |

One bad thing about using an old battery is the amount of current that is readily available to melt your test leads or your device under test when a short or near short occurs. (IMG:style_emoticons/default/headbang.gif) That's why we have fuse blocks. Especially for a novice, I'd recommend a low amperage power supply.
Also agree that a multimeter is a must - most troubleshooting is determining whether or not power is getting there, measuring resistance, and determining continuity. An inexpensive multimeter for $15-$30 can do all this just fine for occasional use like working on the teener. As previously mentioned, search the web for a little education on electrical theory and on schematic reading. Keep asking questions as you get further along... |
