In case your wondering...and I know you are. The stock 90amp alternator in my truck is NOT enough to drive both the Taurus fan and the A/C. dam! I forgot that I WAS going to upgrade to 136.

Had been putting off hooking up the hi speed side all summer, then I had a wiring epiphany, the A/C relay is a DP/ST. You can use it to isolate the low speed temp side when the A/C is on.

But seems the 9amps the low side is drawing is too much when the A/C is on. Cycling is not a good thing. Lease now I have a "need" to put in the 136 now.

 

How is your fan and your a/c drawing too much while driving? That fan must use a LOT of power!

 

Why did some trucks come with a 90 and some with the 136?

 

If you go looking at the 170A alternators with external rectifiers you might conclude that it's cheaper to replace the fan setup than the alternator.

 

The Taurus fan is a hog. The alternator in the car was/is 130 amps. A 136a for the 1500 should be a good match for this setup.

If it won't pull both the A/C and e-fan while sitting in the drive way I'll not use the A/C while driving until either the power issue is resolved, or I go back to a *gasp* mechanical fan . I'd rather roll the windows down then chance messing something up.

 

Didn't the majority come with 117? That one seems to be the most numerous at the salvage yards.

 

Your right, my bad

 

They make an alternator/***** pump combo? Badass!

 

my manhood would never go anywhere near anything that is connected to my engine's moving parts haha

 

Ya done lost me there, squirrels...
