- Convert rectifier only
- 12-70 Amp Press Fit Avalanche Diodes
- Maximum Durability case mount diode CS-144 design
- Typically 308+ Amps at 1800rpm
- Typically 130+Amps at 650rpm
- Similar to but outperforms the Penntex PV-4V
Makes a 420 amp capable alternator - requires drilling case and similar rectifier as pictured - but not includex
Tools needed are 4 inch or larger c-clamp, deep and shallow sockets to press in and remove the Diodes, heat gun for shrink tubing, drill with 31/64 DRILL Bit, and Diagonal cutters, which are sometimes known as side cutters or dikes, are the basic tool for cutting the existing Diode leads or trimming the new ones.

You need this to power a decent size Gas Generator.
An alternator is limited in output by it's rectifier diodes. Three 80 amp diodes on one side of the rectifier can pass 240 amps, so six can pass 480 amps and this is limited mostly by the stator being triple or quad wound. Also continuous heavy load can produce considerable heat. A CS-144 pulls air from the rear, while a AD-244 or DR-44 blows air from the front but not across the rectifier because it is outside the case. This design pulls air across the rectifier first and with no rear plastic on the rectifier cools 50 to 75 percent better for greater reliability. If you really want to go back to stock nothing else internally is changed.
For maximum output use a custom quad wound 240 amp stator
Directly replace the CS-144 family alternator of the same mounting style
** 70 amp Avalanche Diodes and six eye crimp connectors
***** You cannot run a welder with this alternator and the right supplemental circuitry because it has Avalanche Diodes. *****
You need to have an alternator type like this. Add exchange core of $100.
We use these on all GM vehicles depending on the vehicle or engine application. Depending on how set up it could reduce cost per mile fuel use to 10% of the total you pay now. ($4,000 per year down to $400 per year)
You can mount dual units. We can provide GM's wiring.
4 hours consulting included. If you want us to ship this item without setup, it is then no longer eligible for EPA and CARB EO or waiver. See 40 CFR Part 85, Subpart F
40 CFR Part 85, Subpart F is . . .
Subpart F--Exemption of Aftermarket Conversions From Tampering Prohibition Sec. 85.503 Conditions of exemption. (a) As a condition of receiving an enforcement exemption from the tampering prohibitions contained in section 203 of the Act, an aftermarket conversion certifier must certify the aftermarket conversion system, using the applicable procedures in part 86 of this chapter, and meeting the applicable standards and requirements in Secs. 85.504 and 85.505, and accept liability for in-use performance of the aftermarket conversion system as outlined in this part. (b) As a condition of receiving an enforcement exemption from the tampering prohibitions contained in section 203 of the Act, an aftermarket conversion installer must: (1) Install a conversion which has been certified as a new vehicle or engine, using the applicable procedures in part 86 of this chapter, and meeting the applicable standards and requirements in Secs. 85.504 and 85.505; and (2) Accept liability for in-use performance of the aftermarket conversion system as outlined in this part.
Now here the relevant language above is (b)(2) which requires the manufacturer to "accept liability for in-use performance of the aftermarket conversion system outlined in this part"
That means if we design and build it, we must make sure you use it according to the law and that we can have the power to do so. The only legal way to do this is to license it, even IF it is CARB exempted by order, and the only way we can be assured our product will not be tampered with after design is to license it only and/or lease it out.
The EPA memo makes clear that only closed loop systems can be now used, and this in conjunction with the manufacturer maintenance provision means we must maintain control over being able to - and being the only party who can - adjust the ECM which is an after market part and uses our after market part system. Thus we can only license our systems and lease the items out - not sell them outright.

This is a remanufactured GM type 12 and 4 o'clock stye AD244 style DR44 high amp alternator now with 12 diodes and high amp stator and rotor - and it requires an EXTERNAL REGULATOR - not included. It can put out up to 450 amps continuous and can put out 230 amps at idle (650 rpm). GM never made such a thing - but Penntex industries did for the PX-1000 and 2000 series regulators for heavy duty Truck and Ambulance service. Theirs had 35 amp diodes and was rated for 200 amps - this unit has 80 amp diodes ALL inside the case so it fits as a stock unit does
Fits Chevrolet, Delco, Isuzu, Delco DR44G and many others
This unit has enough amperage output capacity to run a decent sized Hydrogen Generator and the vehicle easily
Amp pass capacity is the values of half of the Diodes added up which is 75 times 6 is 450 amps. In all likelihood the alternator would likely overheat under continuous load at that load. Since an in case regulator would burn up fast - an external heavy duty Ford style set at 14.3 volt set point is included with introductions how to wire it. Available with two wire or four wire regulators, and the internal regulator can be used by simply plugging in two wires.
If you are looking at this you know why you need it. Compare to Penntex Special Order - ships in 10 days. Stock photo - available in most ALL mounting configurations - 12 and 6, 4 and 8 (shown) and pad mount. This is a popular alternator also known as the 22,SI and is available in most all the mount configurations thereof by special order. Will fit where CS144 and 130 style alternators fit.
