Unless you need more juice, I'd go with the AC Delco 10SI.

I would just go to your local NAPA. Life-time warranty.

I still like the 12 VDC units despite global warming, ethanol and Obama.

I'm into shiny stuff under the hood. For that reason alone I bought a power master polished aluminum. 100 amp. My original was inop anyway. Parts to rebuild them are relatively cheap but polishing the case is time consuming.

Justin Beiber would disagree. And he is controlling the USA and Canada now. Perhaps even Panama.

Don't forget he visited Cuba also.

I think he's being subjected to mind control from that monkey he abandoned in Germany. No other 19 year old with too much money, too much fame and insufficient slaps upside the head has ever done such crazy things in the history of the world.

The yoots today are revolting.

Same here. Been there, done that. I had a long talk with Justin Bieber, but it appears not to have done any good.

You mean he couldn't convince you to smarten up and act your age?

The opposite. He suggested I try to act his age. He wanted me to go to Panama with him. I'm out of sun screen, so I begged off.

Another common problem for overcharging depending on wiring is the ignition key to alternator signal. This is what the regulator read as voltage. If there is any parasitic resistance on this wire it will read lower voltage and compensate by higher voltage output until it reads the correct one.

Myself, I like and run a TuffStuff brand alternator. Hard to pass up American made.
depending on your current and your planed accessories you may wish to bump up your amperage. And then of course your wiring.
With twin electric fans and a EFI system I run a 140 amp alternator and it is working well in my application.
