Does anyone have an alternator on their T? Buckeye sells them and states this on their website about them:
"The 12-volt version is capable of 80 amp output; the 6-volt version is capable of 40-amp output"
Model T's only have 12 AWG wiring in the charging circuit... and its 100 year old wiring to boot, nowhere near the ability to handle that kind of power if the alternator decided to put out it's max power.
Anyone seeing any issues?

Re: Does anyone have an alternator conversion on their T?
Yes, I have 12V alternator, I love it. Many trouble free miles. Its from Larry Becker. Its about 13 years old or so. Of course we lost Mr. Becker a few years ago. His famous saying was as long as he was here it was guaranteed. I have his 12 volt starter also. Never a problem.
As Tom Sellick told Marston in the movie Quigley Down Under, I told you I dont have much use for handguns, I never said I didn't know how to use them!

My '24 came to me with a Becker 6V one wire alternator. It has worked perfectly for the 12 years (and counting) that I've owned the car.

Re: Does anyone have an alternator conversion on their T?
We also had the Larry Becker 6 volt alternator with a self-contained regulator on our 26 Runabout for 15 years, with no problems... Seem to be the only fix since going through a few Fun Projects regulators on the generator . Now running a fine generator and regulator detailed and rebuilt ...... By Jeff Stevenson..... Do you know him ???...... Thanks again.

Re: Does anyone have an alternator conversion on their T?
I run a 6-volt alternator from Snyders - no issues at all. I’ve never noticed more than about 15 amps maximum charge rate on the ammeter. Once the battery’s fully charged, it slowly drops off to just a few amps.

Re: Does anyone have an alternator conversion on their T?
I have a Buckeye Altenator w/ 12volt conversion. Only 1 problem with Bering failure after years of good operation. Buckeye replaced the unit quickly, good folks to deal with & a good quality product. Also using 12Ga input wire, good idea to install fuse link on input wire & if you're running a stock engine and trans, put blue Locktite on altenator case screws to prevent them from becoming loose from the normal vibration.
