on a 94 ls how many amps of power are at the cigarette lighter

 

hmmm... i don't know this one... do you have a multimeter?

 

The fuse is a 15A fuse. Which means the wires probably won't handle much more.

I replaced it with a 20A fuse, since I kept blowing the 15A with an air compressor. So far, the wires haven't burned. Hopefully I don't set my interior on fire...

 

What are you plugging in?

am trying to figure out what resistor to use so i can hook up a computer fan to the cars power seeing how i am thinking about putting a small computer in my dash just trying to do all the math before i start buying parts a putting it together to find out something won't work etc.

 

let us know how it works out

 

What's the spec on the fan?

 

it is a dc 12v 1/4 amp is wat it consumes what is the voltage then

 

i have no clue

 

Get a multimeter and read the resistance on the fan. When the car is on I'm pretty sure the output is 14.4 volts, don't know the amperage, but technically that will vary depending on what you plug in. Use V=iR to find the current flowing into the fan since v=14.4 and R is whatever you measure it at. I'd probably put an inline fuse on the fan so you know it won't get too much current.

 

thank you for everyones help i forgot all about ohms law

Heh, sometimes paying attention in class pays off.

If you are going to install a computer, I highly recommend finding a DC/DC regulator/transformer. You don't want the computer to suffer from the voltage changes that happen as the car is driven.

Even the PC fan will change rpm as the voltage changes. I rigged many PC fans to run on 7VDC for silent computer cases (when heat isn't a concern) and others to run on 17VDC for overclocking, by splicing into the + or - 5VDC lines depending.

 

sayin i did not pay attention in class is just assanine because the reason i forgot about ohm's law is the fact that i am lucky to use that equation about once a year
