Additional wire to blower motor control - picture?? - Page 2 - ZR-1 Net Registry Forums

Which pulley you use depends on the alternator. CS144 type, even 200 amp version, may have to stay with OEM LT5 pulley to avoid over spinning (caused by smaller pulley).
I am running hairpin type and running 2.2? dia. pulley since the manufacturer insists these can handle higher rpm.

If you install the heavier cable, do you still have to change the alternator?
Thanks,
Nelson

Heavier cable might help but not much by itself. Increasing water pipe size alone won?t do much without increasing the water.

Thanks Yun, That was a good analogy.

I don't have a 200A alternator, but I felt adding a NEW wire in parallel with my 30year old Wire would help regardless. Those wires are not fully sealed from elements and I am quite sure resistance of the wiring in my car has gone up in the last 30 years.

Now, I did a few things to my alternator (Keep in mind our CS-144 is the early model)
-Used the larger capacity Stator from the late CS-144
-New Rectifier (Heavy Duty)
-New brushes

-Used OEM Regulator and Rotor.. this along with LED lights everywhere helps eliminate some of the major loads..
