Additional wire to blower motor control - picture??
 

I want to do the mod that Haibeck mentions here - running a parallel wire from the battery to the blower motor controller to reduce the voltage drop at the blower:

Does anybody have a picture of what this looks like at the blower motor controller end? Do you simply splice into the existing red wire close to the connector? Or does the connector get repinned in some way?

At the battery (+12 distribution) end, do you use a fuse?

Thanks!

Nobody? Someone must've done this...or had Marc do it for them?

I spliced it on close to the connector and insulated it with heat shrink.

Thanks, Yun! Did you use a fuse at the other end, if so what amperage?

Here you go, just popped the hood and took some photos and hope it helps.

Thanks!!

I considered splicing in fusible link but did not. Looking at Charlie?s Z, Marc did not splice in any fuse nor fusible link.

Thanks X2


I am considering doing this also, so I appreciate the pics :thumbsup:

Reading the article and the recommendation from Marc about the 200 amp alternator and going with the 2.6" pulley.....I have a 200 amp on my 94 with the stock pulley which is 2.8" plus depending on how you determine the measurement.....so from what I understand....is that you need to use the 2.6" pulley with a 200 amp alternator.....just need clarification......thanks for any info.....:)

I believe Yun did the pulley change with the 200 amp alternator. Marc kept my pulley stock and just went with the 200 amp alternator. It makes a good difference in the amount of cold or hot air flowing out the vents. According to Marc, went from 10mph to 14mph!

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,

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..
