Re: Generator to Alternator Conversion

This is great ! All opinions can be correct!

I just want to point out that the charging system has 2 functions- 1- maintain storage 2- operate loads within its capacity.

The problem I and alot of other antique auto owners have is-the early charginging systems were designed for 100 amp or lower batteries .It doesn't take long to recharge a low amp battery (6or12 volt)But this battery is usually not used for what ever reason.So when we use a higher amp hr battery and end up with a hicup of some sorts(flooded engine,closed points ,etc..)We tax the O.E.M system,often to it's breaking point .
In a perfect world-the batttery would maintain a perfect s.o.c .The engine would start on the first try every time,and the plates in the battery would never sulfate....So as we increase the CCA in the battery we use,the time to recharge is also needed.The alternator can do this at a much lower engine speed,of course the gen will do the same but will usally require more time at a higher engine speed.The internal regulated alternators reliability is unmatched.And if you choose one of the alternators that are built into the old style generators,you have the best of both worlds.The alt I installed on my car has a ouput of 17 amps at 700 r.p.m.with the factory Delco pulley.
Just a little fuel for thoughts.
