Resistor wires/OHMs
According to my wiring diagram for the car I'm working on, I need a 15 ohm resistor wire. I know what the wire is, my question is how do I know if its 15 ohms or 30 ohms? How do you measure the ohms and can the wire be cut to adjust?
Thanks
Robert

If you talking about a fusible link.
They are already cut to length and ready to go.
Plus, they're marked.

No, I'm talking about a resistor wire. Totally different thing.

Resistor wires/OHMs
Robert,
Please explain exactly which wire you are talking about. At first I thought you were talking about resistive spark plug wires. ??
Ohms are measured with a Multimeter. The symbol for ohms looks like the number "8" laying on it's side. The scale ranges from 0 ohms(a solid piece of wire), also referred to as a "short", all the way up to infinete ohms(a blown fuse has infinete ohms of resistance). In other words NO current flow can occur in a blown fuse.
"Ohms" are a unit of measure of resistance to current flow. 0 = no resistance and infinete = max.
Generally speaking you cannot adjust the resistance of a wire by trimming it.
Hope this helps,
Lee

Lee, thanks for the info. The wire I'm working on is in the charging system, its part of the wires that go to the idiot light. I can scan in the schematic if that will help. If you can't adjust the amount of ohms in a wire how do you get the amount recommended?
Thanks
Robert

Robert,
Yes, a schematic would be very helpful. If you want we can take this to e-mail. Mine is Lee_watts(No Email Addresses In Posts!)
To adjust(increase) the resistance of a piece of wire you add a resistor of a known value in line with the wire to achieve the desired total. It your case you would need a 12 ohm resistor in line with the wire. The only important feature of this resistor will be it's "wattage" rating. Resistors can be picked up at most any Electronic supply stores. Even Radio Shack carries them. I would need to look at the schematic to give a guess of what wattage 12 ohm resistor you would need.
