Alternator replacement

[PJambo]

My A127 45-amp alternator died. It has two wires to the big post and a small spade connection. If I replace it with a 65-amp alt, does the small spade wire get a new connector and go to the small post? I'm referencing the images here: http://www.rovahfarm.com/defenderignition.htm

Or, am I going down the wrong path and there's a better (fairly drop-in) option than the 65-amp?

V belt or serpentine?

Since you live in a sizable city, I'd look into having it rebuilt locally.

V belt. I could get it rebuilt, but if I can upgrade fairly easily, it'd be worth it to me.

Years ago I bought a local parts store "lifetime warranty" alternator.

Kept my o.e. unit and had it rebuilt locally.

I've had the parts store replaced...criminy, it's more than 5 times under warranty and kept the rebuilt o.e. unit as spare.

Yes, I know, I ate the core charge...its worth it to me to have a spare as well as a unit that I can have replaced almost anywhere in the country within a day at the longest.

YMMV

3478-360-M91 or 12088n part number. It's a crossover to a Massey furgeson tractor alternator. I've had mine for years, no issues, direct fit.

You can even swap over the stock pulley as it may be smaller diameter. (better low rpm charge)
