12v Generator vs Alternator

Postby EZ » Tue Jan 19, 2016 2:36 pm

Dropped this here as well as the Farmall 130 tab.

Hi guys,
My F130 has an old beater of an alternator on it.
The original generator mount was modified to fit the alternator.
However, the alignment is poor at best.
I have some 12v generators (starter generators for 10hp Briggs&Strat), but they should deliver what I require for charging.
These gens were also equipped with a regulator.

My plan is to install the gen and regulator in place of the alternator.

Never did like the bulky size of the alternator, plus no weather protection for them.

Do you see any positives (no pun intended) to this application, or know of any negatives?

Thanks.

Not sure if the combo generator would work or not, but a good ole standard gen/reg set-up will---Sounds like they didn't know what they were doing when they put the alt on!
I would go with a alt. BUT that is only MY pref.---gens. are fine too, I have both on my tractors! thanks; sonny

If I understand starter generators correctly, they use a relay to isolate the Voltage regulator from the generator and send current to the generator, where it turns like a motor. After the engine is started, the Voltage regulator takes over and it generates current.

since all the wiring to have it as a starter-generator is external, I don't see any problem with using one as a generator only. The only one issue may be the available current, as the systems that used them were usually small batteries and low-power lights.

Before you use it, I would take it apart and ensure the bushings/bearing are in good shape - since they were in direct drive with the engine all the time, and the one Starter Generator I saw used oilite bushings on both ends, there is a chance the bushings are shot.
