Chevy Suburban CS144 Series Extreme Duty Dual Rectifier Alternator Upgrade & Adaptation

1996 Chevy Suburban Alternator Upgrade

For this and later years you can also upgrade to the AD244 series Alternator, click here for details

Here is an installation of our 250 Amp Extreme Duty Dual Rectifier CS-144 Alternator on a '96 Chevy Suburban owned by Jim Stovekeni of Custom Auto Radio based in East Hartford, CT. He was kind enough to send us pictures and a description of what was required to fit this bad boy onto his 350 motor.

The picture to the right is before the surgery, with the stock, puny 105 amp CS-130D Alternator.To install the alternator this is what Jim says:

&lquot;Hi guys, Here is a description of the install. All I had to do was remove the heater hard line from the water pump and replace it with a 5/8" heater line. For the 3/4" line, I removed the quick disconnect at the intake manifold behind the alternator. I replaced it with a street 45 elbow and a long 3/4" heater line water pump fitting and routed it over from valve cover to the heater valve under the air box. Also, there may be a plate behind the original alternator held on by two boats. You must loosen the alternator bracket to head, and block the bolts to remove the bolt on the side closest to the thermostat housing. Then to upgrade the battery wire, I used 2/0". Enjoy the new powerhouse.&rquot;

Here is the finished installation. Can you see this baby under your hood? Order the Extreme Duty Dual Rectifier Page! Click Here

Alternators produce AC current, just like the current from your house wall outlet. Then it uses a bridge rectifier, typically with 6 diodes, to convert the AC current to DC for the battery and vehicles electrical system. With Dual Rectifiers, you get 12 Diodes, which spreads the current load over a much larger area making the alternator twice as durable and twice as efficient at converting the AC current it makes to DC. The many benefits include: less heat build up, less current loss, higher amperage output when hot, more power at idle. Plus, the service duty and life increases substantially. When the rectifier heats up the diodes won't pass as much amperage through them, therefore, the amperage output drops. With our double rectifier alternator you have twice the amperage carrying capacity and double the cooling surface area to keep the diodes cool. This all adds up to MORE POWER, LESS HEAT PROBLEMS and GREATER RELIABILITY.

Universal Alternator Brackets and Accessories Makes Alternator Adaptation easy

Remember, you don't pay a core charge so you get to keep your old alternator. Contact us if your not sure of your application. A great choice for installation on non-GM vehicles and other conversions.
