sde Posted January 21, 2005 Share Posted January 21, 2005 I am about to install the V1, but I don't know what wire to tap into. It will need to tap in under the driver's side. I need to find a wire that turns off when the car is off. I have a multimeter but I don't know how to use it for this. Can anyone tell me what setting to put the multimeter on to test a wire? OR , what wire I should tap into? signed, n00b Link to comment Share on other sites More sharing options...
rao Posted January 21, 2005 Share Posted January 21, 2005 Step back. Get an add-a-circuit fuseholder (you will need the mini size, any auto parts store should have them) and look at the fuse descriptions on the fuse box door and pick one that is on only when the car is running. http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=071-580 Rob IF YOU CARE ABOUT YOUR CAR YOU SHOULD NEVER DRIVE IT Link to comment Share on other sites More sharing options...

sde Posted January 21, 2005 Author Share Posted January 21, 2005 i appreciate the links and suggestions, but i already have the wire clamp to tap into a wire, and i already have a multimeter. all i need to do is test a wire to see if it is hot when the car is on, and not when the car is off. can't i do this with a multimeter?

Blaze Posted January 21, 2005 Share Posted January 21, 2005 I just recently got a multimeter for such projects, and I don't know how to use mine yet either...so I'm interested to see if someone can post some tips for beginners. Link to comment Share on other sites More sharing options...
avs Posted January 25, 2005 Share Posted January 25, 2005 Turn the multimeter to read Voltage DC. If the car is on, you should get somewhere between 12V-14V. Link to comment Share on other sites More sharing options...
Blaze Posted January 25, 2005 Share Posted January 25, 2005 I'll give that a try, thanks for the tip. Link to comment Share on other sites More sharing options...
danbart Posted February 1, 2005 Share Posted February 1, 2005 Use the DC (direct current as opposed to AC Alternating current which is what your wall socket puts out) function. Place one probe on the hot wire and the other on a good ground. ( car frame, bolt). Making sure you get a good connection. Not having a proper ground is the most common cause for electrical problems. Make sure the metal ground you touch is not painted or varnished in any way. I reccomend using a fuse tap rather than a wire splice.

rallispec Posted February 2, 2005 Share Posted February 2, 2005 might be out of the way for you to get access to - but the power wire going to the cigerette lighters lose power when the car is off. (i couldnt find any that turned off with the car in the fuse box or on the drivers side) I had to tap into it when i installed my XM radio.
