Hi All,
I have a 1994 K1500 w/a 350 that i gave to my son recently and we are doing a father son project. After reading the threads, it appears that the HIGHEST FACTORY amperage alternator swap is the AD244 for this vehicle. Am i correct? We are in the process of building a pretty serious stereo (about 4.5K watts), winch, lights, E-fan, and will need dual alternators to power this set-up. A Big 3 is already in place with 1/0 gauge cable and dual 1/0 main power to the cab). Without having to reinvent the wheel, i have a few questions and i hope to find some answers here.
1. If the AD244 is the most current alternator swap for this vehicle, which donor vehicle would i find the highest amperage alternator in? Hoping for 200+ amps each.
2. Am i correct that the AC Delco PT2145 Alternator Conversion Jumper Harness is the correct 'Pigtail Harness' to order?
3. Would anyone happen to have a link or diagram of a dual alternator bracket, with a set of plans with enough details and dimensions, so i could make one in my shop? I have the tools and can fabricate, that's not an issue.
4. Considering we will be using 2 alternators in parallel (with dual batteries), how does the 'Pigtail Harness' come into play in this scenario? I assume i need 2 of them. Is the wiring straight forward, or will the wiring be different in some way?
5. The 'L' Wire (Charge Light Indicator) will be soldered to the AD244 yellow harness wire, correct? Its my understanding the 'L" must go to a resisted terminal (not just a 12 volt) and must have a resistor inline, correct? What type of resistor is required?
6. The blue sense wire goes to the junction block on the firewall, correct (or is it used on this year model)?
7. Not sure about 'I' and 'F' (Field Engage/Excite Circuit) pins mentioned in other threads or if it's need in this case since i don't currently have a AD244 to look at.
8. My truck has a tachometer. How do i wire this considering the AD244 has a pin to measure RPM?
9. Any idea what belt should be used for this set-up?
10. I have seen mention of an AD244R. What is the difference between an AD244 and an AD244R?
11. What are the benefits of removing an AD244 4 pin and swapping it out with the updated 2 pin voltage regulator and is this helpful in this scenario?
12. Am i missing anything?
Considering the AD244 comes on many of the Duramax engines and the alternator is specifically designed for that vehicle to put a lot of voltage out at idle, it would be great in this application since this vehicle will idle and need lots of current at idle. Many of these come with huge amperage ratings as a factory option, 125, 145, 160, etc. With that stated, i assume these alternators for diesels also RPM governed to diesel RPM's. Meaning, they cannot be used on a gas burner because of the difference in the RPM between the vehicles? Can changing the pully size alter this and make it work-able on a gas burner (if this is an issue)?
Thank you all for your input!
