Good Evening from the US. I have been experimenting with a delco alternator for a while now doing anything from charging batteries to producing higher voltages for tools and lighting. However I have unfortunately in the past wired something backwards and poof went the regulator. I am also rebuilding a 105 amp alternator and modifying it to be more like the older SI series for purposes of experimentation. In my research to rebuild or build from scratch a suitable alternator regulator I have basically found four different designs and would like some input or information on what I should try to optimize in order to make a rugged dependable regulator that can perform and do what I need of it. I am looking for a proper well designed regulator for my delco CS 130 105 Amp alternator I rebuilding to be more like the 10 SI for experimenting with coupled to a petrol engine. This is the first regulator I found and is remarkably similar to the delco design. The problem is that it is temperature dependent and is setup for 13.8 volts. The normal delco output is 14.4 which is standard in autos in the US. This regulator also has no protection other than a 0.18 Ohm resistor and a extra diode. Regulator 1 This is the design I am leaning towards do the simplicity of the whole thing and the fact that is almost identical to the original regulator that blew up in my first alternator. Option two is this regulator but I have not been able to find much other than the link here? Regulator 2 I guess no one has built this one and wrote anything about it as I have found nothing? Option 3 Regulator 3 Option 4 and the one I should probably use as it offers advantages over the others. Regulator 4 and the preferred option What I want to know is how best to do the following 1. add the ability to charge in 13.8 Slow charge, Charge in normal 14.4 volts, and for charging my future wind turbine batteries possibly obtaining 15 or 16 volts for deep cycle batteries. my mill will consist of deep cycle 6 volt batteries wired for 12 volts feeding a inverter. However down south we do not get a lot of wind in the summer so I will have to use a gas or diesel system to pickup where the turbine leaves off. I would like to use a three position selector switch with 14.4 volts being the normal position. And the other outputs selected depending on what type of batteries I am charging. 2. I have been looking at the following site with interest in implementing the design into my alternator and would like to know how to do so since I am building a new regulator from scratch. AltMod1 Altmod2 This is basically what I described above as being what I am looking for and interested in incorporating into my new regulator. 3. Do to the possibility of regulator failure for whatever reason I have been looking at adding crowbar protection as described here Protection 1 Protection 2 Protection 3 Protection 4 Informational 4. For those following my post regarding the use of caps with auto alternators a good point was brought up regarding the use of a three wire system instead of the 1 wire setup my 10 SI has now to stop from loading the engine and stalling the engine on startup. My question is in regards to the design of my new regulator and how to go about making one unit for a three wire setup and how to make one unit a 1 wire self excited regulator like the original. On the delco 1 wire alternator the one connector marked L is the connection to a red indicator and switch. When the switch is on and the engine off the red light is lit. When the motor starts the light goes out with indicates the alternator is putting out. So in my new regulator where about's does this connection need to be made so I can still use my indicator light?
