My alternator is gving my trouble. I had the voltage regulator replaced last week and new bearings installed because the voltage was spiking, but now it's now not giving me enough voltage and I'm either going to have to get it fully rebuilt or replaced. I would like to get the same type again since it works great in my pulley system. Does anyone know what kind this is??? (there was a tiny sticker on the back that came off that said 140 amp but no manufacturer).

Best guess, looks just like my Summit, with the plug, for the extra wires.

Looks like a polished case 10si, turned into a one wire. I have the same thing , but a 12si. I don't know, but could the plug be removed and it be turned into a three wire. ( mine has the plug also, remove the plug and there is a regulator in the one I have) :confused:

I want to know if it can be converted also.

Its a 12si case turned into a 1 wire. The front pulley and fan have been changed. 3-wire is much better for automotive applications. I would buy a 12si (about $95 from AutoZone) and either change the pulley and fan or change the whole case. You will only have to add 1 wire to the voltage sensing location on your horn relay if stock and 1 for your dash light.
I believe you have to change the internals to convert it back to 3-wire, not sure about that.

Thank you guys... It has been used as a one wire alternator since day one in my car. I'm meeting with the previous owner tomorrow to ask him a few questions... hopefully he can remember where he got it and what type it is.

I think that my first call on Monday morning is going to be to the generator/alternator shop that "Fixed" it last week. Strange how it was putting out too much voltage before I took it in, and now, it's not putting out enough?

-If I do end up replacing it.... Do you think that I should still go with a 140AMP?
