I cant find a direct link to a chart but go here: http://www.faa.gov/certification/aircraft/av-info/dst/43-13/Ch_11-05.doc then schrool to page 11-31 that will give you a good chart. Use the 14V range, decide how many feet the wire will be, find the amprage draw of your accesory. Now just use a ruler to read the chart. If you are between two sizes, use the larger size. There are other considerations (like is the wire by its self or in a bundle, is it a continuous use item or intermitent). There is a chart that takes these things into consideration by laying three curves over the chart I listed but I can't find it on line.
Patientce, I was searching for it for you. I'm still looking for the other chart. I accually found it in a print manual, if I don't find it on line soon I'll scan it.
Sorry about that...didnt mean to come across as "hey a-hole, where is the chart?" /forums/images/graemlins/grin.gif /forums/images/graemlins/rotfl.gif
JUst wondering if you had an idea of where I could find one.
Thanks, you da man /forums/images/graemlins/peace.gif
Scan of the one you have would be cool too /forums/images/graemlins/thumb.gif
Btw, did you ever get a rear axle for your truck?

No, the one I thought I had lined up ended up being no good. One thing I did just find out though, it has 3.73s not 3.42s. The carier bearings are GONE and it moves so much I thought it had 3.42s untill I pulled the cover. /forums/images/graemlins/crazy.gif I guess its good I didn't buy that other one.
I give up, here is the scan:
Accually I gave up a couple hours ago and had to run to the store. I was hoping someone would post one before I got back. But no you guys made me fire up the scanner /forums/images/graemlins/grin.gif
Here is an example; We are using a "12VDC" system which is more like 13.7V so go to the 14V scale, lets say you need a piece of wire 3' long, and your lights draw 20A. To find wire size follow the diagional 20A line untill it intersects w/ the horizantal 3' line. It falls between 18-20, BUT lights would be considered continuous duty so you can't go below "curve 2" (assuming you didn't run the wires in a bundle), you must stop where the 20A line crosses curve 2-between 16-18. You must use the larger size so you would use a 16GA wire, that is 3' long for your 20A lights. But if you ran your wire in a bundle it would need to be a 12ga. Make sense? If you print the chart it will be easier to use. A clear straight edge is also helpful, especially if you needed to do 25A or anything else that doesn't have a line printed on the chart.
