LS1 ONE-WIRE Alternator ??? LS1 ONE-WIRE Alternator ???
Where do I get one that will last longer than 5 minutes ? I have wasted 2 weeks , countless hours of driving to and from the Alt shop and the shop that the car is at ( well over $25 in wasted gas ) trying a local vendor that sold me a " Brand New " Alternator that each lasted a mere 5 minutes each !? I have now blown over $150 over this ordeal and the place is unwilling to reimburse me for their lack of quality parts. ( Plus the cost of a replacement Battery since the car has to keep being driven back to the shop under Battery power alone, since the Alternators keeps crapping out )
Anyone know of any other places to get a LS1 ONE-WIRE Alternator ?
Thanks in advance for your help !

Why not run a factory alt? its only 2-3 wires including the battery cable. I know the 1 wire is probably a cleaner install, but at this point, if they keep dying it might be easier to just run another wire or two.

Anyone have any contact numbers for a replacement ? I am needing to order one ASAP ?
If your using a 98 harness, do you have the exciter wire correctly wired up ??.. that being with either a light blub or a resistor wired up to term B on the alternator.
Failure to do so will result in failure of the alternator!

That's how I have my 98 alt and harness setup. Resistor on the exciter wire running to the alt from harness. No issues and charges fine, but it's only got maybe 100 miles on it so far as it's not too much fun driving an untuned t-rex

I dont have Any resistors or Bulbs since I am Not using the original Voltage Regulator, so I am not even using plug on the back of the Alternator since I have a One-Wire Alternator and Voltage Regulator.
I want to do everything in my power to Never Ever use the ECM controlled plug on the back ( Where the Resistor would be used if you were to use the ECM plug off the Alt).
There are tons of One-Wire LS1 setups out there, how are they getting away with it and Not using the ECM Plug that requires that stupid resistor ?
One-Wire Alt = Good
ECM Plug with Resistor = Bad ( more wiring computerized BS to brake or go wrong. )

I have a friend that rebuilds alts for a living. I did a carb swap and had him convert my fact alt to a 1 wire setup and never had any problems. What exactly did he do....im not sure but it worked fine.

I am trying to get a Refund from them but its not working out for some reason.
Switched power to exciter wire with resistor inline.... if it makes you feel better you can run the switched source from something other than the pcm. In the end if you take the 5 minutes required to do that you might have a working setup. Your call, have fun.

All the ECM is doing is supplying the alternator with a 5vdc signal to tell it to turn on. The stock LS1 alternator is a one wire alternator. All the wire to the PCM does is act as an ON/ OFF switch. Just use a stock alternator with resistor inline to a ignition power source.

I Went Through All That Bs With Regulators Being Bad Many Many Times (almost A Year's Worth)
Eventually I Went To Autozone And Got Me A Duralast And It Has Held Up Fine To My Needs More So Than My Very Expensive, Verry Unreliable Custom Built Alternator

i used to modify the Ls1 harness for the V8 rx7 guys. i've done 98s and 99+
i know that on the 99+ the alternator wire go directly to the compuer, while the 98 gets power thru the BCM.
On all the harnesses i modified i'd add in a 470 ohm resistor. "This resistor will reduce the voltage to the alternator charge
enable circuit and prevent the circuit from burning up. the resister can be
anywhere in the wire."
Hope this Helps
