1990 Ford Bronco 5.0L

[caravanmike]

My bronco has a Meyer E47 snow plow on it, and the stock alternator is just not enough to supply the amperage It needs.  I just use the vehicle to plow my driveway, so I don't want to put a ton of money into it.  I have two 650 cca batteries that came with the truck.  What do you suggest as far as an alternator that would do the job?

It looks like your current alternator is a 2G series, which are not easily upgraded, I would suggest upgrading to either a 6G or a 4G alternator, I'm not exactly sure on the fit, though.

I conferred with our senior tech and believe upgrading to the 3G would be your best move. You can't upgrade the 2G alternator because of a fire hazard concerning their power output plug. http://alternatorparts.com/Ford_3G.htm should have everything you need, just be sure to note your make and model in the customer comments.
