RENAMED & SOLVED - CS130 to CS144 Alternator upgrade (INFO)

[Beretta1234567]

The CS144 Alternator fits in place of the CS130 using the CS130 fan, just drill a new hole for the one mount and turn the 2.5 inch black bracket upside down for the new hole location.

160 amp for $200.

I've had one on my car for the past 4 years with no problem.

Just FYI. 105AMPs at 12 volts is something in the neighborhood of 1300W. More if its generating 13+ volts.

There aren't going to be many that need a heavier alternator, unless you are demanding more from the system.

Your setup sounds typical. Mine does the same thing, I just flip it to neutral when not moving, been like that for many years, and through 2 alternators. Just used to it.

But as long as its moving and whatnot, it holds just about center on the gauge or higher. It only drops down if I stop, with lots of things running and such.

I doubt that the heavier alt will fix your problem. You may want to upgrade with the big 3 or at least go through your wiring for the alt and all the grounds, make sure all your connections are good and tight and clean.

Edit: I run all LED external lighting, but I do use load resistors for the turn and rear brake lamps, I run fogs as well as headlights.
I have a 200W amplified sub in the trunk and a 200W HU unit. I do not have A/C at present, but even without it I can get it to drop below charge point while stopped, in gear, and with several things going. Again, its been like this as far back as I can remember.

You are probably running the CS130 style alternator, which is typically found in 90-105amp varieties.

You can modify one to push out more amps and run cooler:

The problem with the CS130 is that they can get hot, even at stock levels, so adding more amperage output will kill one pretty quickly if you're not careful. Plus you lose idle speed charging efficiency by "hotrodding" the windings on the CS130.

My full suggestion, you can upgrade to the CS144 alternator, which is bigger and can handle much higher loads, while charging better at idle and every other RPM. Most vehicles only need to enlarge some holes or file down your mounts to get one to fit in the stock place.

The CS144 alternator should fit, it's just gonna take some fiddlin' with it to get it to work. From all the threads I read, the worst they had to do was enlarge the bolt holes and file down some extra space for the alternator mounting ears to fit. Nothing major IMHO

I don't know exactly what constitutes a CS144 other than being an HD alternator option for many GM vehicles (mostly service vehicles and plow trucks). I would call and ask Advance to verify yourself, the website doesn't give ME enough option.

Just because I do not know; What does HD alternator stand for? High Density?

heavy duty

Correct!!!!

Sorry, I spend a lot of times in the GM truck forums and forget that it's not common knowledge to all

Why do you have a 225 ohm resistor?
