Re: How to replace the original Prestolite alternator by a new 1 wire alternator
If the Delco 10si will mount correctly, you simply eliminate the field and excite circuits.... just install wire caps on each one.
Connect the charge lead to the + terminal, and make sure that the chasis negative is connected to the engine block.
The thing with the single charge lead 10si, is that it's self exciting.
These need to see approx 1,200 + RPM before they self excite.
Once excited, they remain excited at any RPM, until shut down again.
Also, the 10si is available in what they call a "three wire" (actually four wire, if we include the chasis negative).
The 10si can be made into either a single wire, or a three wire.
