6 volt generator vs alternator

[koates]

Hi there, well that's a shame you have not tried to find the fault with the generator. There may be no problem with the armature and only some other simple fault or even the regulator. As stated in the above posts, alternators are not without there fit up and operating problems. Read Kurts #8 post again. Also most of the delco alternators only have a small front bearing (smaller than the ford generator) which was never designed to carry the weight and load of a heavy metal fan on the pulley. Try harder and fix your original generator. Regards, Kevin.

how about the bearings going out, with a fan for radiator cooling?

What was the second wire used for?

Charlie NY is the best in the world....plus he has a Cool old barn.

One of the best Ford guys I have ever met

hope all is well Charlie

For now it was a toss up between CG alternator bracket and pulley or a PowerGen from speedway.
Will delco internals fit in a stock generator case?
Thanks

No you need a small alternator, I used a Nippon? 12 volt and had to put reverse polarity diodes in and an adjustable voltage regulator which I can adjust through a small hole in the rear cover. You also need to machine a shaft adaptor to extend the shaft to fit the Ford pulley. The Delco I think came with a Ford generator mount attached, it was just bolt on and use the same battery wire that is there for the generator. I had the 24 volt stator installed after I tried it and didn't like it. The 24 volt stator made it perfect.

No voltage at all coming out of the generator.
I took the generator apart and the commutator (sp) has closed Circut to the shaft. Brushes look new and couldn't find anything wrong with the field coils.
I put the generator back together and tried to motor the generator with the belt unhooked and voltage regulator disconnected. The armiture post was going completely to ground.
The inside was very clean, no signs that anything burnt up.
I have not taken it to a shop as non are close to where I am.
I may rebuild the generator but at isn't going to happen overnight and I would like to get the car going sooner than later as we have a pretty short summer.
Will the smaller bearing wear out faster? Probably but if it last 20000 miles instead of 200000 miles I'm probably okay with that.
The loads may be greater but the speed will be half with the larger pulley especially when you consider a a Sbc will rev a lot higher that a flathead.
G.M. has the slow speed charging problem solved.
Fitting isn't really an issue from what I've read.
I may go back to a generator once I get it straighten out but I probably have a spare gen and reg in the trunk on long hauls.
I switched to an alternator on my 58 gmc after a regulator failed 3 hours from home.
On my 46 chief 1600 kms from home I ditched my original generator after it failed and went to brand new generator with built in voltage regulator and had no more problems.

Thanks

It is just has to do with the way it is wired internally. There is a slight price difference between the wiring methods and I was using an external voltage regulator (for a wiring terminal) anyway so went with the two wire setup.
