Has anyone changed to a 6 volt alternator?

[BobT-47P15]

At the recent swap meet, some fellow I spoke to said "I changed my 6 volt generator to a 6v alternator" and

the car did better on charging. 

 

I looked on the net tonight.......there are numerous alternators for as low as around $35 and on up......which look

like a normal alternator.  They do make them in positive ground.  Looks like a different bracket would be

needed too.   Then....two companies make an alternator in a case that looks like a generator.  Those range in

price from around $400 to about $800.  Any experience with this type swap?

yes you can get a 6 volt positive ground alternator they are usually a gm type I bought a 6 volt positive ground 1 wire off a guy on eBay about 5 years ago I used the factory generator brackets with very little fab work I have had no issues with it so far I also bought a kit off the same guy so if I had any issues I could repair it I have to look before I go to work may have his contact info with the kit if I do I will pass it on to you I am sure many others here have also done this swap.. 1 800 962 5745 is the number I have can't hurt to give them a call and inquire about it best of luck ...Dan

This positive ground 6 volt alternator was installed on my D-24 when I bought it. Works great.

I am running one that I bought off of ebay as well.  Had to buy a different pulley to fit the wide belt.  I haven't got the wiring hooked up as of yet but seems to be working fine.

I have one from Quality Power and even got a bracket from them. It's the Bee's Knee's.

I don't ever have to even give it a thought.

Wide belt alternator pulley's are available from several sources. I believe this one came from Summit Racing.

the guy that I bought the alternator from  had them as well

Some of the places selling the alternators listed a mounting bracket.....and some said they had the wider

pulley available. 

 

Can  you hook up an alternator to the battery gauge in the dash to show charging?

If you mean ammeter, yes. Run a heavy wire, 10 or 8, from the output terminal of the alternator to the ammeter, and Atherton the battery terminal on the starter relay. If the meter reads backwards, just reverse the ammeter connections.

on my 52 I unhooked the battery wire from the regulator and spliced on a section of wire to the alternator may not be the correct way to do it but it has been this way over 5 years and works as it should as does the ammeter I used 48 pulleys on my engine so I am running the wide belt I used the wide pulley from my generator with no issues so far
