An OEM 3G can put out 130 amps - about double what your stock alternator puts out.Euphoric306 said:oh alright, makes sense except that 79-93 is the third gen mustang lol.
but thats neither here nor there, as they say
anyway, unless they put out much more amperage, whats the big dealio of swappin one in?
Simply stated, no. The 3G will put out more amperage at idle than a 2G (they tend to run at a percentage of capacity at idle, and since the capacity is double, the output at idle is greater [though not double]). That was not what you asked, but it led to my next thought. With my 2G, it would struggle to maintain 13.6-14.4 volts if I had anything turned on. So while I was not discharging, I was not charging the system or powering accessories as well as I could have been with the 3G. And I dont discharge at idle at all. The 2G output at 670 RPM was not all that great.Euphoric306 said:yea i was jk about the gens. kinda figured whatcha said
just a little clarification, if you dont have any aftermarket stereo or anything, then the 3g will only put out factory amperage (~65-75)? but then if you've got stereo and fog lights that work, etc. then it'll pull more and you'll need the wiring adapter? thanks people, late
I think I misread you earlier. I would do the wiring upgrade with the alternator upgrade, even if you dont anticipate using more than 65 amps of juice. You want to have the wiring up to par with the alt. It is easy to get the stock alt into a state of diminished charging or discharge, and in the same situation on a 3G, its performance will not diminish. That can lead to burned stock wiring or a fire.Euphoric306 said:yea i was jk about the gens. kinda figured whatcha said

It's cheap insurance to handle the increased amps. The stock fuseable link setup were barely up to par(and not even good electrical practice) for the stock alt.
