LOL. Right now I'm the guy who can't sleep. I'm hoping he's got the whole T-bar dilemma sorted out. But i haven't gotten a straight answer from him. Gonna have a helluva rake going on if he drives it like that!

get some sleep! I'm a college student I'm allowed to be up now but need to rest up. Going for three weekends I've f'd up in a row

When all else fails shop for truck parts...hey look a radiator I don't need..but shiny

LOL. Looks like both of us are browsing ebay. Just ordered a blend door actuator for the grand prix. Also pricing head gaskets for the truck. Those, SC gaskets, water pump, belt and a couple more odds & ends & I'll have her ready.

Look at it like a water hose. Amperage=pressure Voltage=flow.

I don't much care for the very high strand counts. It is flexible but wears much easier. The resistance of a 1ga wire over 10-12ft is pointless to argue over if you are using copper. They are essentially the same when talking about this application. Anyways; heres some math/physics for the nerds For No. 12 AWG Table 8 of the NEC does list two different DC resistances for stranded and solid copper. DC resistance per 1000 feet for solid is 1.93 ohms For stranded the DC resistance is given as 1.98 ohms per 1000 feet. So solid should have a slightly higher ampacity. If we use Table 310.16 of the NEC to determine RCA and substitute into the Ampere calculation we can find the approximate differences in ampacity. From Table 310.16 using 75 degrees C as the ambient. I = 25 amperes, TC = 75 degrees C, and TA = 30 degrees C and RDC = 1.98 ohms per 1000 feet or 0.00198 ohms per foot. This converts to 1980 microhms. From I (in kiloamperes) = SQRT(( TC-TA)/RDC*RCA)) Or RCA=(TC-TA)/RDC*I*I Or RCA = (75-30)/1980*0.025*0.025 RCA = 36 thermal ohm feet For stranded, I = 0.025 kiloamperes from the table For solid No. 12 copper I (in kiloamperes) = SQRT ((75-30)/1930*36) or I = 0.0254 kiloamperes Then the solid No. 12 copper would have a 0 .4 ampere increase in ampacity. This is a 0.4/25 *100 or only a 1.6 per cent increase. Considering that ampacity tables are approximations, this increase in ampacity does not exceed the error of approximation.

Well here we go brew. Gotta throw in some physics from an old college bud who was big into Cal based electronics. I just set up the pde's

Not when your talking low voltage. I work this for a living. Electrical is my thing.

The difference is very minute.

That's my thing too. Anything with laws or physics.
